09.11.2007 (VNY) Fixed a bug that could result in a crash of
the task when processing crowded fields (SSC-SPR-3700);
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); Added a parameter enabling the output of
an additional region file that contains newly detected point-like
sources (zero-order features);
20.10.2007 (VNY) Fixing a bug that could result in a crash of the
programme when processing crowded fields (SSC-SPR-3700)
08.07.2007 (VNY) Fixing a bug that results in a wrongly
calculated available spectrum length of the target (SSC-SPR-3694).
15.05.2007 (VNY) Resolution as to the close (olmost overlapping)
spectra is increased. Discrimination of spurious sources improved
(SSC-SPR-36660).
15.04.2007 (VNY) More improvements in the field spectra extraction
02.04.2007 (VNY) Improved the field spectra extraction
by allowing slightly fainter spectra to be extracted (SSC-SPR-3644)
29.03.2007 (VNY) The code is cleaned up, the possible division
by zero operation is eliminated (SSC-SPR-3658).
27.03.2007 (VNY) A bug causing a subscription error for
the array sourceXcoord is fixed (SSC-SPR-3657).
12.03.2006 (VNY) 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.
09.11.2006 (VNY) Adjusted to the changes in other OM tasks related to
the more accurate computation of the OM grism source RA and DEC positions
(SSC-SPR-3633)
03.07.2006 (VNY) 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
27.02.2006 (VNY) The slight inconsistency between the
code for scaling the spectrum counts and the wavelength
calibration file is removed (this problem was reported in SSC-SPR-3588).
12.12.2005 (VNY) The algorithms for spectra identification and
classification are improved (SSC-SPR-3552)
30.10.2005 (VNY) Generation of empty spectra FITS-files in the
case of too small windows in suppressed (SSC-SPR-3534)
25.10.2005 (VNY) A bug introduced during the previous upload is fixed
18.10.2005 (VNY) A warning message is introduced for the case
when the OSW is too small for extracting any spectrum (SSC-SPR-3526)
26.09.2005 (VNY) Fixing a small bug, which could cause a crash
on some non-standard data sets (SSC-SPR-3522)
12.09.2005 (VNY) Reducing the used stack memory (for compatibility with
most of the systems).
07.09.2005 (VNY) The computation of the coordinates for zero-order
spectra is made uniforme for all the possible cases (i.e. the coordinates
are computed using the centroiding method - SSC-SPR-3515)
14.07.2005 (VNY) A bug in the Marquardt optimisation code
is fixed (SSC-SPR-3439)
08.06.2005 (VNY) protected against stack overfilling, which was
causing a crash on some machines.
06.06.2005 (VNY) 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).
22.02.2005 (VNY) 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)
27.01.2005 (VNY) The backgorund interpolation limits
across the spectrum were corrected: before that, the
reference points for the interpolation were the edges of the
spectrum strip and not the points where the background was
estimated (SSC-SPR-3433).
01.10.2004 (VNY) 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
for the task omgrismplot.
08.09.2004 (VNY) 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)
27.07.2004 (VNY) two new (optional) parameters were
introduce to allow controlling the name of the output
source list file and the possibility to switch between
extracting the single target and all field spectra.
A new output (ASCII) file is created that contains the
extracted spectra region files (SSC-SPR-3365)
22.07.2004 (VNY) Restored the compatibility with the
interactive task omgsource (which was lost in the version
omgrism-1.1.11), SSC-SPR-3360
21.07.2004 (VNY) The spectra identification
numbers in the file SPECLI are made consistent with those
from the file SWSRLI (SSC-SPR-3358)
15.07.2004 (VNY) The target spectrum is placed in
the first position in the output file with spectra
(SSC-SPR-3356)
13.05.2004 (VNY) 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.
23.02.2004 (VNY) A small bug introduced in the previous
upload was fixed. The task was working always in the regime
designed for omgsource (SSC-SPR-3257).
19.02.2004 (VNY) Protected from crushing when called by omgsource
16.01.2004 (VNY) Criteria for selection of zero-order
images at the edge of OSW are adjusted (SSC-SPR-3214).
10.12.2003 (VNY) Spectra labelling in the source list file
is made compatible with omgsource
04.12.2003 (VNY) Extraction of undetected spectra included
02.12.2003 (VNY) Parameters spectrumlength and src2spectrum
are removed as misleading; fluxes are computed.
05.11.2003 (VNY) Parameters for image smoothing are removed
03.11.2003 (VNY) Parameters for the spectrum extraction region
are introduced
27.10.2003 (VNY) Created as a new task, SAS-SCR-116
