omgchain (omgchain-1.8.1) [???]

Meta Index / Home Page

Change history

• September 17,2008 New parameter (removescatteredlight) is introduced to enable removing scattered light features by the task omgprep
• May, 01, 2008 Modified the call to omgrism plot in order to produce the PostScript file with spectra extraction regions plotted over the grism rotated image.
• May 22, 2007. The default parameter for the width of the spectrum extraction region was set to 8 pixels because this is what actually was used in the task omgrism due to a small bug. The bug was fixed in Omgrism-1.17 (accompanying the SSC-SPR-3660) so that omgchain is also adjusted to keep the spectrum extraction region the same as it was before before.
• January 31, 2007 The file names are modified such that they include the symbol with the observation mode idenifies (S, U or X). Previosly this symbol was fixed (S) since it was thought that the observations are always sheduled (fixing SSC-SPR-3646)
• November 11, 2006 Grism sky image is generated by the omatt task. The parameters are adjusted to the more accurate computation of the grism source coordinates (SSC-SPR-3633).
• June 09, 2006 Using the retirn flag from omgprep-1.1.1 (non-zero in the case of too small images) to stop processing the current exposure because the spectra are not extractable from too small images (SSC-SPR-3606)
• May 30th, 2006 An additional task introduced into the code (omatt) in order to compute the right ascensions and declinations of the field objects (SSC-SPR-3605)
• September 07, 2005 The documentation corrected (SSC-SPR-3508), the dependencies file is made consistent with the latest version of omgrism.
• September 09, 2004 The spectra list file is now generated for both values of the parameter extractfieldspectra. That is, when extracting even a single (target) spectrum the the SPECLI-file will contain only one line. But having always the same set of the output files would simplify understanding the results by the user (SSC-SPR-3382).
• July 26, 2004: V1.0.8 A new optional parameter is introduced (extractfieldspectra) to switch between two modes: extraction only the target or all the available spectra in the field
• July 15, 2004: V1.0.7 Default options for the spectra extraction region are changed from 3 to 6 pixels to avoid the possibility of missing some of the spectra (SPR-3355)
• May 20, 2004: V1.0.4 Engineering-2 sub-window files are sorted at the input according to their names in order to ensure combining of these sub-windows into a single full-frame image (SSC-SPR-3324).
• February 03, 2004 V1.0.2 Two parameters needed for omgrismplot task are activated (scalebkgplot and plotflux); the task omgrismplot is modified to produce plots labeled with the spectra identification numbers.
• February 01, 2004 V1.0.1 The task is protected against crushes when the verbosity level is higher than seven. The input parameter extractionmode is activated.
• December 04, 2003 V1.0 Extraction of undetected spectra included
• November 04, 2003 V0.3 Parameters rationalised
• October 29, 2003 V0.2 Paths to the input and output directories corrected
• October 27, 2003 V0.1 Created as a new task (SAS-SCR-116).
