group OM to correct the location of the task web page.
Version 1.24 - 2008-11-06 (VNY) +(src/omgrism_mod.f90) A bug
is fixed, which was causing a crash when processing
images with crowded fields (the parameter for the smoothing
window size was reduced to zero for a field with more than 550 sources)
Version 1.23 - 2008-10-01 (VNY) +(src/omgrism_mod.f90) Added some
useful log messages
Version 1.22 - 2007-11-07 (VNY) The same as 1.21, the version number
was increased to align it with the SAS patch release
Version 1.21 - 2007-11-07 (VNY) +(src/omgrism_mod.f90) Restoring the
omgsource flag when extracting the target spectrum: in the
case when omgrism is called from the interactive tool omgsource
the target spectrum shouldn't be extracted (fixing the SSC-SPR-3702)
Version 1.20 - 2007-11-07 (VNY) +(src/omgrism_mod.f90, config/omgrism.par)
Added a parameter enabling the output of an additional region
file that contains newly detected point-like sources (zero-order
features)
Version 1.19 - 2007-10-20 (VNY) +(src/omgextraction_mod.f90) Fixed a
bug that could result in a crash of the task when processing
crowded fields (SSC-SPR-3700)
Version 1.18.1 - 2007-07-08 (VNY) +(src/omgrism_mod.f90) Fixing a bug
that results in a wrongly calculated available spectrum length
of the target (SSC-SPR-3694)
Version 1.18 - 2007-05-22 (VNY) +(src/omgrism_mod.f90) A small bug fixed
Version 1.17 - 2007-05-21 (VNY) +(src/omgrism_mod.f90, omgextraction_mod.f90)
Improving distinguishability of close spectra (fixing SSC-SPR-3660)
Version 1.16 - 2007-04-15 (VNY) +(src/omgrism_mod.f90) More improvement
in the field spectra extraction (SPR-3644)

(fixed SSC-SPR-3657)
Version 1.12 - 2007-03-12 (VNY) +(src/omgrism_mod.f90) The quality flag
type in the input source list table is changed: now it can be
either int*8 or int*16 (fixing SSC-SPR-3653). A warning message
is isssued when the number of input sources exceeds 1000. Such
a field cannot be processed yet (SSC-SPR-3643). Also the target
detection is improved: in the cases of a bright target overlapped
with a first order-features such a target was sometimes not detected.
Now it is working better.
Version 1.11 - 2006-11-09 (VNY) +(src/omgrism_mod.f90) Adjusted to the
changes in other tasks related to more accurate computation
of grism source sky positions (SSC-SPR-3633)
Version 1.10 - 2006-07-03 (VNY) +(scr/omgrism_mod.f90) A slightly more
complicated analysis of the target position and brightness
is introduces in order to prevent missclassification of obvious
bright targets (they sometimes are classified as "default
extraction" although being correctly extracted) - SSC-SPR-3617
Version 1.9 - 2006-02-27 (VNY) +(scr/omgrism_mod.f90, omgextraction_mod.f90)

during the previous upload of the task was fixed (SSC-SPR-3533)
Version 1.5 - 2005-10-18 (VNY) +(src/omgrism_mod.f90) A warning
message is introduced in the case of impossibility of
extraction the spectrum due to the smallness of the
window (SSC-SPR-3526)

omgexcratcion_mod.f90, omgrism_mod.f90) Fixing a small bug,
which could lead to a crash when working with some non-standard
data sets (SSC-SPR-3522)
Version 1.3 - 2005-09-12 (VNY) (+src/findsourcelist_mod.f90) reducing the
used stack memory, since in some systems this resource is limited>
This change is additional to fixing SSC-SPR-3515.

The computation of the coordinates of the zero-order spectrum
is made the same for all the possible cases (SPR-3515)
Version 1.1.30 - 2005-07-14 (VNY) (+src/omgextraction_mod.f90)
A bug in the Marquardt optimisation code is fixed. This was
affecting the optimal extraction mode (SSC-SPR-3434). The main
(default) extraction mode remaines unchanged.
Version 1.1.29 - 2005-06-10 (VNY) (+src/findsourceslist_mod.f90,
omgrism_mod.f90) Additional check is introduced in order to ensure
that the bright zero-order features have right coordinates
(they could be erroneous because of numerous bright spots
due to coincidence losses and modulo-8 noise). Fixed SSC-SPR-3479
Version 1.1.28 - 2005-06-10 (VNY) (+src/findsourceslist_mod.f90)
A bug introduced in the previous version is fixed
Version 1.1.27 - 2005-06-09 (VNY) (+src/findsourceslist_mod.f90,
omgrism_mod.f90, omgextraction_mod.f90) Cleaned out of the unused
variables (to reduce the number of warnings durung the compilation)
Version 1.1.26 - 2005-06-08 (VNY) (+src/findsourceslist_mod.f90)
Protected against excessive nesting of stack memory, which
was causing a crash on some mashins (SSC-SPR-3468)
Version 1.1.25 - 2005-06-06 (VNY) +(src/omgrism_mod.f90,
omgextraction_mod.f90, marq_mod.f90)
Additional checks are introduced to ensure the correct extraction
of the target spectra in the cases when its zero-order image is
badly affected by the modulo-8 noise (SSC-SPR-3465). The common
block is deleted from marq_mod.f90 (this was not used but caused
a build failure on the Mac).
Version 1.1.24 - 2005-05-23 (CB1) +(src/omgextraction_mod.f90
Ammended routine to fix build problem.
Version 1.1.23 - 2005-02-22 (VNY) +(src/omgextraction_mod.f90):
the negative counts that could appear when subtracting the
background from a faint spectrum are taken into account.
Omitting the negative counts might result in a slight overestimation
of the spectrum (SSC-SPR-3444)
Version 1.1.22 - 2005-01-27 (VNY) +(src/omgextraction_mod.f90):
correction of an additional small (logical) bug related

a small bug related to wrong background interpolation
limits across the spectrum is fixed (SSC-SPR-3433).
Version 1.1.20 - 2004-10-18 (VNY) +(src/omgrism_mod.f90) The bug
related to the missed target on the full-frame low-resolution
images is fixed (SSC-SPR-3408)
Version 1.1.19 - 2004-10-14 (VNY) )+src/omgrism_mod.f90) An additional
patch improving the solution of SSC-SPR-3407 is added
Version 1.1.18 - 2004-10-14 (VNY) (+src/omgrism_mod.f90,
+src/omgextraction_mod.f90) Logical sequence in determination
of the target is improved - to eliminate the possibility of
labelling the default extraction region as target
(SSC-SPR-3407)
Version 1.1.17 - 2004-10-07 (VNY) +(src/omgrism_mod.f90) One more small
bug is fixed related to SSC-SPR-3398
Version 1.1.16 - 2004-10-05 (VNY) (+src/omgrism_mod.f90) A small bug
is fixed, which was causing imroper labelling of the target
spectrum (SSC-SPR-3398)
Version 1.1.15 - 2004-10-01 (VNY) (+src/omgrism_mod.f90,
+src/omgextraction_mod.f90) The procedure of decontamination
of the output spectrum, in the case when it is overlapped with
zero-order features, is removed (SSC-SPR-3396).
It is supposed that this procedure is more appropriate
in the task omgrismplot.
Version 1.1.14 - 2004-09-08 (VNY) (+src/omgrism_mod.f90,
+src/omgextraction_mod.f90) Interpolation of the
wavelengths and fluxes at the end of the flux
calibration array is improved in order to avoid
missing points at the end of the output flux table
(SSC-SPR-3381)

+config/omgrism.par) A new spectra region file
is introduced (ASCII) that contains extracted spectra
regions, SSC-SPR-3365

omgextraction_mod.f90) The spectra identification
numbers in the file SPECLI are made consistent with those
from the file SWSRLI (SSC-SPR-3358)

omgextraction_mod.f90) The target spectrum is placed
into the first position in the output file
(SSC-SPR-3356)

omgextraction_mod.f90) The spectrum extraction mode
keyword is passed to the omgrismplot task through the
header keyword EXTRMODE. The keyword TIMEDEL replaced
with DLAMBDA (SSC-SPR-3319). Some other small changes
are made in order to imrove task's performance.
Version 1.1.8 - 2004-03-03 (VNY) (+src/omgrism_mod.f90) Rejecttion
criterium for spurious sources is improved
Version 1.1.7 - 2004-02-23 (VNY) (+src/omgrism_mod.f90) A small bug

crushing when called by omgsource
Version 1.1.5 - 2004-02-12 (VNY) (+src/omgrism_mod.f90) Selection
criteria for specra are improved (spurious sources excluded)
Version 1.1.4 - 2004-02-02 (VNY) (+src/omgrism_mod.f90) The output
fuxes are set into the wavelength range define by the CCF
(SSC-SPR-3244)

images at the edge of OSW are adjusted (SSC-SPR-3214);
default real variables are replaced with the explicitely
declared real(kind=double) ones.
