ChangeLog for omflatgen
=======================
Version 1.8.1 - 2002-05-29 (CB/SRR)
___________
Documentation updated

Version 1.8 - 2001-01-08 (CB)
___________
DEPEND file ammended.

Version 1.7 - 2000-12-19 (CB)
+ (src/omflatgen_mod.f90) Code that was to use slew data removed.
+ (config/omflatgen.info) Optional parameters IndexSet and signoise removed.

+ (doc/omflatgen_description.tex) - Documentation updated (SPR 2652)

Version 1.6 - 2001-11-22 (JBa)

+ (doc/omflatgen_description.tex): fixed documentation

Version 1.5 - 2000-13-07 (CB)
+(config/omflatgen.src) Attribute "CONTENT = OM OSW FLAT FIELD"
changed to "CONTENT = OM FLATFIELD" (SPR 2127)


Version 1.4.1 - 2000-11-07 (CB)
+(config/omflatgen.info) "om" added.
Version 1.4 - 2000-10-03 (CB) Changed "DEPEND" file to correct "make
check" error.

Version 1.3 - 2000-09-26 (CB)
+ (src/omflatgen_mod.f90) Program now computes the signal-to-noise
ratio for each pixel of the final flatfield image and stores it in
the output fits file. The minimum, maximum and median
signal-to-noise ratios are also calculated and stored.
+ (doc/omflatgen_description.tex) - Above change documented.


Version 1.2 - 2000-09-21 (CB)
+ (src/omflatgen_mod.f90) Program now uses as many slew
observations as are necessary to construct a flatfield with the
required signal-to-noise ratio.
+ (src/omflatgen.par) Parameter "nslews" removed and parameter
"signoise" added.
+ (doc/omflatgen_description.tex) - Above change documented.


Version 1.1 - 2000-07-21 (CB)
+ (src/omflatgen_mod.f90) Program modified so that a flatfield can
be produced by a call to "CAL_omPixelSenseVariation" - the default
if no index file is specified.

+ (doc/omflatgen_description.tex) - Above change documented.


Version 1.0 - 2000-06-21 (CB)
-----------

+ (src/omflatgen_mod.f90) - Modified so that the full file names
are constructed properly from the entries in the index file.
(SSC-SPR-1847) - Code added to ensure that the 4 flatfield files for each slew
(obtained from the archive file) are used in the order of increasing
windowX0. Config file ammended so that the parameter "nslews" (the number
of slews) has to lie within the range 1-500. Program now issues a warning
message if any pixels with zero or negative counts are found in the slew files.

+ (config/omflatgen.info) Added

Version 0.4: 14 Jan 2000

Code to remove lamp illumination implimented. However relevent CAL call is
not yet available.

Warning on number of slews included.

Version 0.3: 5 Jan 2000

Added optional "number of slews" parameter

Open SPRs :

SPR 1103 : Missing slew produces cryptic error message.
SPR 1102 : All zeroes or negative numbers undetected.
SPR 1101 : Task doesn't check slews are from same OBS/EXP/OSW.
SPR 1100 : Input and output files missing keywords.
SPR 1099 : Coding standards.
SPR 1098 : Run time errors and nslew error.
SPR 1097 : Parameters in task description don't match *.par file.
SPR 1096 : DAL does accept string columns, file needs FITS input.
SPR 1095 : More description in omflatgen task description needed.

Version 0.1: 19 August 1999

SPR 1094 closed: Removed spurious files from src.

Version 0.1: 30 June 1999
