Change history

01.10.2008 (VNY) Added some run-time messages
09.11.2007 (VNY) 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)
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
