Summary of important changes

This release includes a number of new tasks and features and a larger number of bug fixes and improvements, all of which are detailed below.

• Production of quiescent particle background (QPB) data products by the mean number of discarded lines in EPIC-pn data: The new task qpbselect has been introduced to generate QPB spectra or images from EPIC-pn FF data scaled by the number of discarded lines. The number of discarded lines are calculated by evselect from housekeeping data and written into keywords, DLMEAN, DLMAX in the output products.
• An option to modify an input event file or create a new one has been introduced in evqpb.
• Introduction of a rate-dependent correction in EPIC-pn BURST mode data (using CCFs EPN_CTI_0053 and later).
• Preparations for running the esas tasks with calibration files in standard SAS CCF format.
• A new spatial expression, "IMAGE('imagefile')" which selects data from a spatial region where the image is non-zero, has been introduced into evselect.
• Positions may be specified in celestial (RA, DEC) cordinates for a circle, box or annulus region expression within evselect.
• Spectra created by evselect have the keywords BACKFILE, ANCRFILE, RESPFILE keywords set to "NONE" by default.
• slconv: solved problem with large radii for large DEC positions.
• omsource has been removed pending refurbishment.
• SAS mosaic images have been made compatible with ds9 version 8.1 by the introduction of the RADECSYS and DATE-OBS keywords.
• SAS has been upgraded to GNU C/C++/Fortran 9 by changes to the utils, dal, omvariability, selectlib, omgsource, omphotom, and omcat packages.
• epicspeccombine : improved error handling and documentation.
• Source detection: various updates including use of esplinemap in smoothing mode and the correction of the pile-up estimate for extended sources.
• The new task emanom has been introduced to get anomalous chip information for the MOS cameras.

Python support

A new infrastructure of Python in SAS has been created around a core Python package named pysas and a small set of new Python packages has been added: sasver, startsas, rgsbkgsmoothing and xmmextractorGUI. pysas allow users to run any SAS native task from pure Python sessions running standalone or under Jupyter Notebooks.

A new version of package pkgmaker, fully recoded in Python, allows now to create the proper structure for new Python packages.

Binaries distributed

This version of SAS is released in two binary versions for Linux, CentOS 7.3 and Ubuntu 18.04, and one for macOS 10.15.7 (Catalina). These versions have been tested and found to run correctly on several other platforms including Linux RHEL 7 and 8, Ubuntu 20 and 21 and macOS Mojave.

ChangeLog

Version 4.28.3 - 2019-02-28 (IT)
--------------
	+ eboxdata.f90: increase (double) counter max_sou to handle large
	  mosaic images in the pipeline

Version 4.28.2 - 2018-04-24 (RDS & IT)
--------------
	+ edetect_io_box.f90: To check whether an input image was empty,
	  its total number of counts was determined, which can exceed the
	  numeric range of thedata type and cause an error (example: 256
	  counts in an 8-bit integer image). The sum has been replaced by
	  the maximum pixel value now for all numeric image types (as an
	  int32 variable to cover all possible types), and by a boolean
	  for the masks. (SPR-7441 ctd)

ChangeLog

Version 0.6.2 - 2020-08-01 (IT)
-------------
	Removed temporary debugging output.

Version 0.6.1 - 2020-07-22 (IT)
-------------
	Dependencies updated.

Version 0.6 - 2020-07-15 (IT)
-------------
	4XMM-DR9s related:
        + Introduced new columns in the source list in catalogue format:
	  N_EXP holds the number of exposures (instrument-level) involved
	  in the fit to a source.
	  OVERLAP (boolean) indicates whether the center of the source is
	  located in an overlap area (N_CONTRIB>1).
	  DIST_REF holds the angular distance of the source to the
	  reference coordinates of the frame.
	  N_BLEND holds the number of simultaneously fit sources (from
	  emldetect's ID_CLUSTER)
        + Added VAR_PROB, VAR_PROB_n, which were calculated externally for DR7s.
	+ Replaced emosaic by the more efficient imweightadd (without
	  weights). Parameter is still called "runemosaic".
	+ Experimental integer keyword "parallel": number of CPUs to be
	  used for parallel processing of the input data (observation-level
	  task calls like attcalc). Requires non-standard module
	  Parallel::ForkManager (if parallel>1)!
	+ Explicitly skip observations loop if only stacking stages are run.
	+ Updated parameters to 4XMM defaults:
	  eboxl_nruns=3 esp_scut=2e-4 esp_snrmin=12
	4XMM-DR10s related:
	+ allow for emldetect's experimental tmpwrite parameter
	+ allow for evselect's zcolumn parameters
	+ Updated pile-up calculation for extended sources (cf. emldetect).
	+ Documentation updated.

Version 0.5 - 2019-02-23 (IT)
-------------
	+ Introduce boolean keyword "compress" to gzip files on the
	  fly. Slows down FITS I/O, but significantly reduces disk space
	  requirements. When starting from a minstage > 1, only input files
	  having suffix .gz or .ftz (case insensitive) are recognized as
	  compressed versions of .fits files.
	+ edetect_stack.pl: Read all input files right at the start-up
	  (in order to ease the compression step).
	+ edetect_stack.pl run_sastask(): pass emldetect command to shell
	  script file if the command length exceeds the maximum argument
	  string length (which is 131072 for most linux kernels) and thus
	  could not be executed directly.
        + edetect_stack.pl, input names: Single arguments are recognized
	  as file names now if a file with this name is found.
	Related to the preparations for 4XMM within emldetect:
	+ stack_sourcelist.pl: Change all tests on EXT_ML to EXT(ENT)
	  after introducing extent likelihoods for point-like sources in
	  emldetect.
	+ stack_sourcelist.pl: Estimate pile-up level for the three EPIC
	  instruments. The total pile-up is the maximum of the
	  observation-level values.
	+ Documentation updated.

ChangeLog

Version 2.16 - 2020-01-10 (JB)
------------------------------
        + Make keyword propagation conditional to their existence
	+ Increase maximum number of regions to 16384 and add a warning
	  if that number is exceeded
	+ Optimize CPU for small regions
	+ Fix 0.5 pixel offset
	+ Add detmasktable parameter to allow writing output in the PRIMARY


Version 2.15 - 2018-02-13 (EO)

	+ This is a new major version of this package including a new GNU
	Public License Text disclaimer required to distribute the SAS source
	code to the Astronomical Community under the terms of the GNU Public

	---------------------------------------------------------------------

ChangeLog

Version 7.6.2 - 2020-07-18 (IT)
-------------
	+ emldetect_mod.f90: split an "if" condition into two calls, since
	  gfortran-9 stopped to accept "mod" with zero apparently

Version 7.6.1 - 2020-07-15 (IT)
-------------
	+ Updated the pile-up estimate for extended sources. To use the
	  counts of the summed PSF models, chip gaps are filled
	  temporarily: Where the exposure map is zero, the PSF models are
	  stored in units of rate in bg_image. Note: bg_image0
	  contains the original input maps and is not touched.
	+ Write source maps only where exp_image > 0, i.e. do not use the
	  temporary values.
	+ edetect_io.f90: Throw warning on missing FRMTIMnn keyword only
	  if missing from /all/ CCDs (single CCDs might be set inactive).
	+ Removed checks and debugging output which were kept from the
	  larger re-write below for testing purposes.
	+ Documentation: Updated references and fixed broken ESAC link.

Version 7.6 - 2019-07-31 (IT)
-------------
        eml_io.f90, subroutine neighbour: initialize arrays with dimension
	nsrc (ll in mlout) instead of max_sou.
	Runtime and memory improvements, mainly for the stacked catalogues:
	+ fftpsf.f90 and psf.f90: Read CAL PSFs only for those images
	  which cover the source to be fitted. Introduce an array ipuse in
	  the main routines, structured as ip, which indexes all images
	  with valid mask pixels in the source fitting region. nuseimage
	  is the number of images involved in the fit to one source.
	+ Limit several arrays to nuseimage instead of the total number of
	  images; part of them were already allocatable: sima in fftpsf.f90
	  and psf.f90, bima0 in fftpsf.f90, scts_scale and scalepsf in emlfit.
	+ fftpsf.f90: bsiz, nx, ny, sec2mm per image instead of
	  instrument, so they can be limited to nuseimage as well.
	+ Replaced the functions bpsf and psf4, which were called per
	  pixel, by subroutines backpsf and backext, which are called per
	  image. The cumbersome rebinning, inherited from old task
	  versions, is kept to avoid changes in source parameters owing to
	  single/double precision.
	+ Note: There is some in-active spare code to avoid repeated PSF
	  rebinning in psf.f90 and to separate PSF rebinning from folding
	  with the extent model within backpsf. Since this update (very)
	  slightly affects the source parameters, it has not been
	  incorporated so far. It could, for example, be considered in a
	  future majore upgrade.
	+ Calculate likelihood array only for pixels with photons: Other
	  elements are 0 anyway.
	+ Make events and mask%mask allocatable, max_par smaller.
	+ Minor cleanings, e.g. removed obsolete ifs for testoutput and
	  unsused variables / arrays.
	+ Experimental: Flag "rateextonly" to (re)fit the count rates and
	  fluxes at given source positions.
	+ Experimental: Flag "simulate" to create background+source maps from an
	  input emldetect source list.
	+ Experimental: Integer parameter "tmpwrite" to write an
	  intermediate source list to the disk every  sources.
	Avoid old use of ambiguous variable name "sum" in fill_arrs.


Version 7.5.2 - 2019-03-08 (IT)
-------------
	Pile-up levels: increase an array size to handle large stacks.

ChangeLog

Version 1.19 - 2020-03-02 (JVP)
--------------
        + src/emosaic_mod.f90

- Write RADECSYS and DATE-OBS keywords for ds9
DATE-OBS is a copy of the DATE-OBS keyword from the first

ChangeLog

Version 2.33 - 2020-02-14 (AI)
------------------------------
	+ (src/edu_simu.c) Centos 7 does not process this memcpy sentence
	properly. The documentation of memcpy warns about the usage of
	this  directive in overlapping memory blocks. Therefore,
	we change the memcpy directive with  memmove. SOC-SPR-7548 fixed

ChangeLog

Version 1.23.1 - 2020-07-07 (EO)
--------------
	+ doc/epiclccorr_description.tex: Due to the change of default to
	UTF-8 in LaTeX documents, documents which include accented letters
	entered from the keyboard, can not be processed and produce an error.
	To avoid such error we must include the directive 
	       \UseRawInputEncoding 
	as the first line in the document. 
	Another option is to add, instead of the previous directive, the proper
	encoding invocation, depending on the encoding used, typically either
	latin1 or cp1252, in the document's preamble, as
	       \usepackage[latin1]{inputenc}
	However, package LaTeX description files do not have access to the
	document preamble, which is provided by sas package file 'package.tex'. 
	But this file is common to all LaTeX documentation so, any change
	there would affect to all documents.

ChangeLog

Version 2.4.2 - 2020-09-10 (EO)
	+ DEPEND: pysas 0.6 -> 0.7

Version 2.4.1 - 2020-09-10 (EO)
-------------
	+ src/pkgmaker/bin/pkgmaker: replaced args by iparsdic in run().
	+ template/python/DEPEND: pysas 0.6 -> 0.7
	+ template/python/taskname.py.in: args -> iparsdic.

Version 2.4 - 2020-09-05 (EO)
-----------
	+ src/pkgmaker.py:
	  * Added check for SAS_PATH.
	  * sasdev is now formed by joining the first element of SAS_PATH and
	  directory sas, either real or soft linked, to the SAS git clone.
	  If not present, shows message and exit.
	  * At start, shows where all new packages will be written.
	  * Added default input option: Take same taskname as pkgname.
	+ template/python/DEPEND: sas-1.603 and pysas-0.6.
	+ DEPEND: sas-1.603 and pysas-0.6
	+ template: Mior adjustments for Python template.

Version 2.3 - 2020-07-21 (EO)
-----------
	+ template/Makefile.python.in: Removed $(PYTHONLIBDIR)/dists from
	CLOBBERDIRS. 

Version 2.2 - 2020-07-16 (EO)
-----------
	+ template/python/DEPEND: Replace common DEPEND file with this one
	with specific dependencies for Python packages like pysas.

Version 2.1 - 2020-07-16 (EO) 
-----------
	+ src/pkgmaker/pkgmaker.py: To ensure updated versions of pkgmaker,
	the pkgtemplate and pkgmakerdir should be based on sasdir more than on
	sasdev. This prevents to outdated versions of pkgmaker.
	+ src/pkgmaker/pkgmaker.py: pkgmakerv replaced by __version__.

Version 2.0 - 2020-04-08 (EO)
-----------
	+ This task is fully rewritten in Python. As such, it uses now the new
	Python infrastructure created for SAS Python tasks.
	+ template: The src subdirectory is now replaced by four 
	subdirectories, one for each type of the four supported programming
	languages: C++(cpp), Fortran90(fortran), Perl(perl) and
	Python(python). Each of these subdirectories include files 
	specific for each programming language that can be used to make
	a package on that programming language. The package is assumed to
	have a single task under src.
	For Python, the template/python subdirectory has the directory 
	structure and includes all the files required to make a Python package
	whose modules can be placed below a given directory under
	$SAS_DIR/lib/python and the executable script, under $SAS_DIR/bin.
	The package could also be built to be uploaded to PyPI, by means of
	the setuptools tool, using setup.py.
	+ DISTRIBUTION: Changed to world.
	+ doc: The pkgmaker.html file is not updated yet. In progress.
	+ DEPEND: Besides the ubiquitous dependency on sas package, now it
	depends on the Base Python package for SAS, named pysas.

Version 1.34 - 2019-12-03 (JVP)
------------
	+ Python template updated templates/src/module.py

Version 1.33 - 2019-10-15 (JVP)

Version 1.32 - 2018-03-13 (EO)
------------
	+ Added templates/src/module.py to support development on Python.
	+ src/pkgmaker: Updated to work with Python based tasks.

ChangeLog

Version 0.9.1 - 2020-10-13 (EO)

-----------
	+ These changes fix SPRs: 7567, 7568 and 7574.
	+ src/pysas/parser.py: 
	  - Added method taskparser in class ParseArgs. 
	    Creates parser and parse args (options and parameters) entered in
	    the command line.
	  - Added method procopt in class ParseArgs. 
	    Identifies immediate options -m, -v, -d, -h, -p and set Exit to

	+ src/pysas/sastask.py: 
	  - Added p.taskparser() and self.exit = p.procopt(), in method
	    processargs of class MyTask.
	  - Added checking of Exit after p.procopt() call in method
	    processargs. Return from method on True. t avoids using sys.exit(0)
	    which is catched as execption SystemExit by interactive ipython
	    sessions.
	  - Added check for Exit in runtask method of MyTask. Return on True.
	+ src/pysas/runtask.py: 
	  - Included code from wrapper.py to handle running non Python tasks.

Version 0.8 - 2020-10-02 (EO)
-----------
	+ Makefile: Added src/pysas/bin to SUBDIRS.
	+ src/pysas: 
	- Added bin/wrapper script. First script in pysas.
	Aimed to run non Python SAS tasks, e.g. taskname, as

		wrapper task=taskname args
	
	where args can be any possible arguments to be used to run taskname.
	These arguments can be either of the form of param=value or
	param='value value value ....value' or any of the options available
	for any SAS task (e.g. -v, -d, -m, etc).
	- Added wrapper.py module to run the non Python task via Python
	subprocess packagei, with all the arguments.
	+ src/pysas/runtask.py: 
	- Modified method in class RunTask to search for all pysas
	packages and put them in list 'pysaspkgs'. Uses pkgutil.walk_packages.
	Any package not belonging to pysaspkgs is considered a non Python
	task, therefore will be run through the run method in wrapper.py module.
	+ src/pysas/parser.py: 
	- Modified processing of version to support also non Python tasks.
	- Modified runext method in line with code used in wrapper.py.
	+ setup.py: Added scripts=['src/pysas/bin/wrapper']
	+ README.md: Updated.
	+ src/pysas/param: Fixed bug regarding the existence of self.xmlFile:
	If no .par file is found for the task, this file is not defined.
	+ src/pysas/sastask.py: Added customized logger with name,  two
	handlers console and file, default logging levels set to WARNING and
	ERROR and specific formatting for each them respectively.  

Version 0.7.1 - 2020-09-10 (EO-AI)
-------------
	+ src/pysas/error.py:

-----------
	+ src/pysas/sastask.py:
	  * Added dictionaries argsdic, parsdic and iparsdic to method
	  processargs. argsdic includes parameters (param=value) entered
	  command line. parsdic includes all par file parameers and their
	  default values. iparsdic is the merge of both resulting in
	  a dictionary of parameters to be passed to any task module
	  for execution.
	  * Modified runtask method accordingly to previous change.
	+ src/pysas/runtask.py: replaced iargs by iparsdic as input
	argument.

Version 0.6.1 - 2020-09-08 (EO)
-------------
	+ src/pysas/parser.py: Removed debug print.
	+ src/pysas/sastask.py: Changed ordering logic for inargs.

	parser, param, error and runtask, are now imprted relatively.
	Added import of .version to get __version__ object.
	+ error.py, param.py, parser.py, sastask.py and runtask.py: Added
	classification of imports.
	+ src/pysas/parser.py: Import of taskname is now absolute in
	import_module,
	+ src/pysas/runtask.py: Import of taskname is now absolute in 
	import_module.
	+ DEPEND: sas package must have version 1.603
	+ README.md: Fixed typos.


Version 0.5.1 - 2020-08-27 (EO)
-------------
	+ src/pysas/param.py: Fix bug while looking for par file.

Version 0.5 - 2020-07-17 (EO)

ChangeLog

Version 1.603 - 2020-09-05 (EO)
-------------
	+ bin/pyset.py: New Python script to set up the right environment
	for Python below sasdev/lib/python. The script is run when the

	on macOS with the rpath method (@loader_path) used to build dylib
	libraries. 
	Added png and xml2 to extralibs lists of paterns.
	+ Makefile.top: symlinklibs target: saslibs is now run with -l and -o
	options at once. Output is produced in file saslibs.log.

Version 1.601 - 2020-08-03 (EO)
-------------
	+ configure.in: 

		     Building with rpath on Linux and macOS 
		     ======================================

	On Linux this is accomplished in the process of linking of the
	executable. For this purpose we use the LDFLAGS variable which is
	defined in the configure as SASLDFLAGS with the following settings
	       
	   -Wl,-rpath,\$$ORIGIN/../lib -Wl,-rpath,\$$ORIGIN/../libextra
	
	These settings allow for any executable in $SAS_DIR/bin to locate any
	SAS internal library, below ../lib, and any extra library, below
	../libextra, starting from its current location at $ORIGIN.

	We must apply the same mechanism to SAS internal shared libraries
	which might have cross dependencies among them. Therefore, in the
	creation of any internal shared library, we must apply the following
	switches

	  -shared -Wl,-rpath,\$$ORIGIN -Wl,-rpath,\$$ORIGIN/../libextra

	This way, internal libraries in $SAS_DIR/lib will be able to find
	their internal dependencies in its own subdirectory and any
	dependencies on external libraries in ../libextra.
	
	On macOS, instead of setting the rpath mechanism at the creation of
	the executable, it is done when building the shared libraries which
	eventually will be needed by such executable, in particular when
	defining their install names (install_name setting).
	Therefore, in the configure, we modify the SHARED_LIB_FLAGS,  as
	follows:

	         -Wl,-install_name,@loader_path/../lib/$@
	
	Then, when the executable looks for the library, it will take
	automatically the position where it is found (@loader_path) as a
	reference to find the library.

	These settings can be switched on or off depending on a new option to
	the configure named 
	
	    --enable-rpath

	If such option is given, binaries and libraries in Linux and macOS are
	linked using the above mentioned settings. Otherwise, they are built
	with the traditional method, where shared libraries required by
	binaries are found through DYLD_LIBRARY_PATH.

	Default value for --enale-rpath is set to yes.

	On linux, when using the -rpath option with the GNU C/C++ linker, by
	default it sets the RUNPATH feature in the ELF binary structure,
	instead of the well known RPATH feature. What is this? It has to do
	with the order used to find shared libraries. This order is:
	First RPATH, then LD_LIBRARY_PATH and finally RUNPATH. Thus, now, the
	latest versions of the GNU C/C++ linker set RUNPATH instead of RPATH.
	If we want to let work RUNPATH, we need to unset LD_LIBRARY_PATH. 
	However, we still could use the old behaviour, that is to set RPATH
	which, regardless of what is specified in LD_LIBRARY_PATH, shared
	libraries will be searched always first where it has been specified by
	the -rpath switch. To make this work we need to pass the following
	additional switches to the linker,

	          -Wl, --disable-new-dtags
	
	In this version of the configure, we have not applied the previous
	switch "--disable-new-dtags", therefore we are setting the
	RUNPATH mechanism, not the RPATH. Therefore, should exist a setting of
	the LD_LIBRARY_PATH, it will take precedence over the setting in the
	ELF header of the binary. 
	
			    Operation with rpath
			    ====================
	When the rpath mechanism is in place, we can unset the environment
	variable (DY)LD_LIBRARY_PATH. This is something we have to propagate
	to the different initialisation scripts like sas-setup.sh, setsas.sh,
	etc. This is not done yet but we expect to do it as soon as this
	mechanismo is tested during the validation phase of SAS 19.

	For a build, the rpath mechanism will not work due to the fact that
	binaries and libraries are not actually located in $SAS_DIR/bin and
	$SAS_DIR/lib. These directories contain only soft links to the real
	binaries and libraries which are located below the directory trees of
	their packages,	typically below packages//src. Therefore, the
	rpath  mechanism can only be put into operation in what we call an
	'installation' of SAS, where binaries and libraries are put physically
	within the $SAS_DIR/bin and $SAS_DIR/lib directories. 

	To make rpath work in a build, which is desirable given that builds
	include extensive tests of the binaries created, we need to replace
	the soft links by real copies of the binaries below $SAS_DIR/bin and
	libraries below $SAS_DIR/lib.

	+ bin/saslibs: Added option -o outfile to put in 'outfile' all the
	output generated by the script. 
	Changed the method to set soft links in libextra.

	+ configure_install: 
		- Enhanced documentation.
		- Check SAS_PERL/perl relationship and she-bang creation.
		- Added check_python function to check for Python in PATH and
		check whether version is >= 3.6.
	
	+ configure.in: TARGET_OS, removed CPU bits; left only OS
	"NameVersion" string.

	+ Makefile.top: Removed LCPU in accordance with previous change in
	configure.in.

	functions chdir and cwd() (from Cwd module), to be able to compare
	properly the $pwd and $pwddir vairables.
	+ Make.include.in: Added lib/python/dists and lib/python/pysas to
	the list of required dirs to be creted below the user's root
	development path, usually the first in SAS_PATH. 
	The dists directory will store the Python sdist and bdist_wheel tgz
	that can be uploaded to PyPI.
	The lib/python/pysas is necessary to replicate
	$SAS_DIR/lib/python/pysas under user's development enviroment.
	+ doc: Updated SAS.pm, latex2html.init. removed script copyxmmdoc.
	Makefile updated accordingly. 

Version 1.598 - 2020-06-10 (EO)
-------------
	+ Make.include.in: Added PYTHON variable as detected in configure to
	allow its use in Makefiles for Python based tasks.
	+ configure_install: Check for perl in PATH and whether or not it 
	matches SAS_PERL user´s setting. SAS_PERL declared mandatory.
	+ install.sh: Changed to end running the configure_install, thus
	any failure can be fixed by re-running it.

	  python with version equal or later than a required version.
	  It is assumed than python required modules, e.g. numpy, astropy, etc
	  should have been installed by means of pip. 
	  * Python required version is 3.6. This way we can still build with 
	  GNU C/C++ 7.1.0 which was designed to work with it.
	  * Removed configure option --enable-force64 and associated variable 
	  FORCE64. 
	  * All builds are 64 bit. There is not the 32/64 indication close to
	  the operating system (TARGET_OS).

	writes a new python file name version.py, filled with SAS release 
	information in the form of constants, SAS_RELEASE, SAS_AKA, etc. 
	version.py is produced by means of 'make data'.
