---------------
+ Time Correlation processing for SAS 6.0.5 defaults to TCS
+ Fix problem determining obs boundaries for TCX records
for in case of multiple exposures present for instrument being
processed
Version 3.111.5 - 2004-07-27 (JSH)
---------------
+ Change TimeCorrelator constructors to avoid calling
other constructors as default parameters. gcc 2.9x doesn't
like that at all.
Version 3.111.4 - 2004-07-20 (JSH)
---------------
+ Update OAL to process TCX data files
- New environment variables used by OAL
- OalServer uses environment variable to
select TCS or TCX (a la ahf/raf handling)
- OalServer then calls TimeCorrelator with
appropriate arguments
- TimeCorrelator updated to process TCX data
- C++ test case updated
- Documentation updated :)
Version 3.111.3 - 2004-06-29 (RDS)
---------------
+ Addition of HBR_OFFSET_DATA type and logic to return the
best offset map for a given exposure
src/Odf.cc/h
Version 3.111.2 - 2004-02-13 (UL - still around :)
---------------
+ more changes to pn AUX data anomaly detection/correction logic to
cope with seen problems in a number of ODFs (see email MJF to
MK/UL dated 2004-01-29):
- relax maximum allowed fractional frame time jitter to better
cope with extended counting mode intervals
- for jumps that are not +/-1s _always_ look for jumps in the opposite
direction within the next 50 frames even if an integer offset
was found that satisfies the 'delta criterion' (=delta must be
integer multiple of nominal frame time); it used to be that
this check was supressed if a suitable offset was found leading to
the introduction of bogus corrections (e.g. Crab ODFs
0411_0153750[2345]01)
- if delta<0: only accept offsets that are odd and that correct jumps
occuring close to the end of a second (FTFINE>40000)
- if delta>0: only accept offsets that are +/-1s or larger than
80% of the gap size
- all other found deltas will not lead to a correction now but just
appear as 'unidentified deltas' in the log
Version 3.111.1 - 2003-12-12 (RDS)
-------------
+ removed f90 interface to RGS diagnostic maps.
+ removed call to hasRgsDiagnosticMap - can use hasSet() instead.
Version 3.111 - 2003-12-11 (RDS)
-------------
+ finished SCR-133.
Version 3.110 - 2003-12-05 (EO)
-------------
+ oal_description.tex typo corrected.
Version 3.109 - 2003-12-04 (RDS)
-------------
+ added the routine OAL_RGSDiagImage to return a diagnostic image
for an RGS configuration (SCR-133)
Version 3.108 - 2003-08-06 (UL)
-------------
+ more changes to the PN-AUX data anomaly detection/correction logic:
* for negative jumps limit the search interval for an offset
that makes the difference between consecutive frames an
integer multiple of the frame time to [|i|, |i|+2] (was
[|i|, |i|+10]); i is value of jump (fixed problem in
0156_0095810401_PNS00300AUX CCD7 reported by MJF)
* supress verification of very large gap size; e.g. in
0362_0124930301_PNS02500AUX.FIT CCD4 there is gap of >177s
corresponding to >30000 missing frames (Burst mode); the frame
time jitter makes it senseless to verify the gap size
* detection of 'premature increments' improved;
0362_0124930301_PNS02500AUX.FIT CCD4 contains a case where old
logic failed
+ fixed very minor problem with output message
Version 3.107 - 2003-07-03 (UL)
-------------
+ pn AUX data anomaly detection+correction logic: there can be blocks
of AUX data whose QUADRANT/CCDID signature is wrong, e.g. they seemingly
stem from different quadrants (see doc comments in src/AusHKaccess.cc
for more info) - the size of these blocks was limited to 25 rows but
0137_0128120401_PNS00200AUX.FIT (source PSR1507) contains an example
of a 31-row block; the allowed size has not been increased to 50 rows
Version 3.106 - 2003-06-27 (UL)
-------------
+ Calculation of signal propagation delay at SAS_OBT_MET_FIT=1,...:
Modified code after confirmation (email Ramon Munoz dated 2003-06-27)
that onboard delays have to be SUBTRACTED instead of added
Version 3.105 - 2003-06-20 (UL)
-------------
+ pn auxiliary data processing: fixed a minor problem in a code branch
that deals with the very rare occurence of apparent CDMU crashes
during an exposure - in this case the determination of pn clock reset
times was incorrect (caused problem with 0104_0111130201_PNS00300AUX)
Version 3.104 - 2003-06-18 (UL)
-------------
+ Implemented SCR 115: oal should not use unprocessed raw attitude file
by introduction of new (optional) enviroment variable SAS_ATTITUDE;
if not set default is to use AHF data; doc updated accordingly
Version 3.103 - 2003-06-16 (GV)
-------------
+ Misc. fixes to make gcc-3.3 happy: include <cassert> and/or
proper initialization of base classes.
Version 3.102 - 2003-05-02 (UL)
-------------
+ bug fix to solve (rare) problem with S/U exposure confusion (seen
in e.g. 0591_0144900101 - unscheduled Timing exposure follows
scheduled Imaging exposure with same exposure number; S/U002)
Version 3.101 - 2003-04-04 (UL)
-------------
+ fixed minor problem with new InstrumentalTimer() I/F
Version 3.100 - 2003-04-03 (UL)
-------------
+ added OalServer::instrumentalTimer()
Version 3.99 - 2003-03-18 (UL)
------------
+ closed SPR 2418: class IPPV should not be public string
Version 3.98.2 - 2003-03-12 (UL)
--------------
+ fixed problem with repeated OdfInfo::server.odf() invocations generating
new instances of OdfInfo::Odf() objects
Version 3.98.1 - 2003-02-12 (UL)
--------------
+ fixed minor bug that would cause an 'unidentified delta' in the pn AUX
data anomaly recognition stage to get reported when there is none;
occurs when wrong-quad entries are present within a period after
a FTCOARSE jumps and before a reset [e.g. 0149_0111100301]
Version 3.98 - 2003-02-07 (UL)
------------
+ implemented piecewise-linear interpolation of time correlation data as
alternative method to global polynomial fit; switched on by setting
second field 'degree' in SAS_OBT_MET_FIT to negative values; doc
updated accordingly
Version 3.97 - 2003-01-30 (UL)
------------
+ small improvement in pn AUX anomaly detection logic related to find
blocks of wrong-quadrant/CCD data
Version 3.96 - 2003-01-30 (UL)
------------
+ skip pn AUX data anomaly correction stage if data is found too anomalous
(e.g. old-vintage SciSim AUX data)
+ catch pathological case that frame time increment is 0 (caused crash
in epframes test harness)
Version 3.95 - 2003-01-29 (UL)
------------
+ much improved pn AUX data anomaly detection and correction algorithm;
should now be able to reliably find all FTCOARSE counter jumps
[Note: Access to EPN_TIMECORR CCF for AUX data anomaly processing
needed]
+ couple of new warning messages about pn AUX anomalies (e.g.
unidentified deltas)
Version 3.94 - 2002-09-11 (JBa)
--------
+ some ANSI C++ compliance fixes (in preparation of moving to gcc>=3.1)
Version 3.93 - 2002-07-02 (JBa)
------------
+ replaced all occurences of 'strstream' with standard-conformant
'stringstream'
Version 3.93 - 2002-07-02 (JBa)
------------
+ Using sstream instead of strstream
Version 3.92 - 2002-06-20 (UL)
------------
+ hasAssociatedSet()/associatedSet() now works for PN DLI data
(association is made by searching for CCD number match in
DLI exposures not later than 15mins after science exposure)
+ internal code change to work around out-of-mem compiler problem
at -O2 on Tru64
Version 3.91.8 - 2002-05-28 (UL)
--------------
+ changed text of new error message introduced with 3.91.7
Version 3.91.7 - 2002-05-24 (UL)

+ issue error message if used with skeleton summary file (odfingest
has not been run)
Version 3.91.6 - 2002-05-03 (UL)
--------------

frequent occurence of FTCOARSE=32767 frames, seen in e.g.
odffix'ed 0053_0121500601)
Version 3.91.5 - 2002-04-26 (UL)
--------------
+ fixed minor problem with pathological exposures shorter than 90s
+ fixed minor problem with rare anomaly in pn PMH data (seen e.g.
in 0175_0132520301_PNX00000PMH.FIT)
Version 3.91.4 - 2002-04-23 (UL)
--------------
+ fixed new problem seen with ODF 0120_0102640201 (this is related
to a 3.91-change to correct for TM anomaly in Crab ODF 0411_0153750301)
Version 3.91.3 - 2002-04-19 (UL)
--------------

empty orbit files (e.g. odffixed data)
Version 3.91 - 2002-04-17 (UL)
------------
+ meliorated robustness against EPIC clock late-reset anomaly
(this fixes problem seen in Crab obs 0411_0153750301)
+ fixed another problem with S/U exposure confusion (e.g. in ODF
0418_0110980301)
+ fixed minor problem with re-calculation of signal propagation delays
+ read entire orbit file instead of just data covering obs window; needed
for recalculation of signal propagation delays in TimeCorrelator

--------------
+ fixed minor problem with determination of ODF location when SAS_ODF is
given just name of summary file

Version 3.90 - 2002-03-25 (UL)
------------
+ introduced fifth SAS_OBT_MET_FIT field: 0/1 toggle switch controlling
whether or not GS handovers in the TC data are ignored (1) or not (0);
in the latter case all TC data after a handover are not taken into
account; default is 1, i.e. all TC data are considered
+ updated doc w.r.t to new SAS_OBT_MET_FIT control parameter
Version 3.89.1 - 2002-03-25 (UL)

velocity at any point in time during the observation
o FrameCounterVector/ObtVector + support classes to perform
the conversion from CCD frame counters to COBT values to
proper event time tags
o support classes for the above
+ a couple of non-backwards compatible changes in the F90 API (therefore
the 1.4->2.0 transition):
o dropped state variables 'status'/verbosity'/'observationStartDate'

handling strategy ('if-error-boom')
verbosity : is now controlled by the environment (VERBOSITY)
observationStartDate: not needed
o added new state variables 'ccdNr'/'nodeNr'/'attitudefromAhf'
ccdNr/nodeNr : the chip/node id
attitudeFromAhf: boolean switch determining whether attitude data
are to come from the AHF or from OM tracking
history frames
o dropped 'OAL_error' routine
o renamed 'OAL_selectType' -> 'OAL_selectScope'
o new auxiliary function 'OAL_toAttitudeMatrix' to convert a
attitude record as returned by 'OAL_getAttitude' into a matrix
representation
o new enquiry function 'OAL_exposureInfo'
o 'directoryName' fields added to structure returned by 'OAL_odfInfo'
+ a couple of tools in the sample ODF directory 'odf' which generate a
dummy Attitude History File, and embryonic EMOS1 periodic HK and
auxiliary files for EMOS1 exposure #1; all are needed for the test
harnesses
+ re-organization of directory structure:
odf : dummy ODF for test harness and example task
src : all C++ sources
cxxtest: tests of C++ implementation
f90 : F90 API, C++/F90 I/F
f90test: tests of F90 layer
doc : documentation
+ test harnesses: extentended to test new functionality (from C++ and
F90);
+ OAL example task: moved to f90test and extended to demonstrate usage
of new features
+ documentation updated to be in line with code changes
+ remaining issues:
o construction of PositionLocator class from data in Reconstructed
Orbit File (ROF) is still dummy - need more information on
structure of ROF before a proper implementation can commence
o construction of AttitudeLocator from OM tacking history data
is not implemented yet - algorithms needs to be clarified and
meaning of OM telemetry to be confirmed (e.g. roll angle)

+ fixed SOC-SPRs:
o 326: Update documentation
o 327: Add oal.tex closely following the template
o 328: Merge v1status.txt and status.txt into description
o 329: Remove spurious files (src/OalAtoms.cc.new,src/OalAtoms.h.new)
+ doc/oal.tex removed - this is now created on-the-fly by 'make ps/html'
