#----------------------------------------------------------------------------- # IRACproc: IRAC Post-BCD Processing v4.3 CHANGES #----------------------------------------------------------------------------- (c) 2005 Mike Schuster, Massimo Marengo (mmarengo@cfa.harvard.edu) (c) 2005 SAO - Smithsonian Astrophysical Observatory Harvard-Smithsonian Center for Astrophysics Smithsonian Astrophysical Observatory 31 JUL 2008 #----------------------------------------------------------------------------- # New for v4.3 #----------------------------------------------------------------------------- New High Dynamic Range (HDR) PSFs, and improved PSF-subtraction routine psfsub_bcd New routine cleanup - deletes unnecessary IRACproc output Routines psfmask_bcd and psfuncrop_bcd now psfmask_fits and psfuncrop_fits Improved image selection based on WCS coordinates in mkmosaic_bcd (WCS_BOX option removed) Improved BAD value handling (esp. coadd_fits, project2D) Improved memory usage (esp. deriv_fits) Improved support for large images in cropout_bcd, backgrnd2D #----------------------------------------------------------------------------- # New for v4.2 #----------------------------------------------------------------------------- New wrapper/log (my_iracproc) for batch processing a single IRAC data set Final mosaic pixel scale is now set with mkmosaic_bcd (instead of fixup). The script refixup will reset the configuration files for an existing IRACproc directory structure. mkmosaic_bcd STEP 6 now writes CREATOR header keyword from first image in bcd image list into final mosaic header - this is the SSC pipeline version Notes for background fitting/subtraction in large mosaics Notes for dark frame subtraction and background registering near saturated sources New routine for coadding individual sub-array image packs before coadding the resulting images with mkmosaic_bcd - this is a significant improvement over previous methods Updated Pmasks from SSC web site Revised setup General improvements to code (subroutines, etc.) New subroutine pedsub_fits for subtracting images, pedestals, etc (replaces pedestal_bcd). coadd_fits now includes options to calculate the minimum, maximum, biased median, division of two images, and patch a PSF peak onto a saturated core (also - improved memory usage, bug fixes, etc.). There are also new methodologies for outlier rejection that are based on the type of pixel stack distribution. #----------------------------------------------------------------------------- # New for v4.1.2 #----------------------------------------------------------------------------- Fixed several bugs in coadd_fits and project2D routines (affects bad values - NaN's, and dimensions of output images) coadd_fits now includes an option to calculate the Absolute Minimum Deviation image Improved outlier rejection for coadd_fits #----------------------------------------------------------------------------- # New for v4.1.1 #----------------------------------------------------------------------------- Fixed minor bug in coadd_fits routine (affects only headers of output files) #----------------------------------------------------------------------------- # New for v4.1 #----------------------------------------------------------------------------- MOPEX option USE_REFINED_POINTING now set to 0 (not used) since S13+ pipelines have improved the pointing inserted into CRVAL1 and CRVAL2 Additional documentation for IRACproc and the main perl and perlDL routines fixup script is now more compatible with other contributed software for IRAC General improvements to code (memory usage, subroutines, etc.) coadd_fits routine replaces coadd_bcd (includes drizzle option and improved outlier rejection) coadd_fits now includes an option to calculate a color image No longer distribute specialized routines for Nearby Stars program Simplified PDL installation outside CfA pgplot is no longer required by IRACproc #----------------------------------------------------------------------------- # New for v4.0 beta #----------------------------------------------------------------------------- Improved outlier rejection for shallow coverage (2-4 frames) Elimination of IRAF dependencies for co-addition Simpler, 5-step process for producing mosaic images Accommodation for performing additional preprocessing of data outside IRACproc Keyword options in mkmosaic_bcd that add flexibility to customize processing parameters Additional keyword options in mkmopex_bcd that help to sort through BCD frames to select only those frames for further processing that are 'on' or 'off' field, as well as within a box specified by WCS coordinates Added the 'mode' as an option for determining the background pedestal in an image - available in all PDL routines that have the option "BACKGRND" Some improved documentation #----------------------------------------------------------------------------- # Beta software for v3.3 #----------------------------------------------------------------------------- 4-step process for measuring photometry Photometry scripts (see HOWTO_PHOT) Script for correlating photometry from up to 4 channels (correlate.pl) #----------------------------------------------------------------------------- # New for v3.3 #----------------------------------------------------------------------------- Outlier rejection improved for high coverage (>~10 frames) Fixed bug in coadd_bcd that caused unnecessary interpolation of images coadd_bcd will now trim PSF-subtracted images to their original size and can subtract multiple PSFs with the "diff" method New routines for masking/cropping PSF artifacts (psfmask_bcd, multimask_bcd, and psfuncrop_bcd) Proc #6: mkmetmap replaces mksrcmap (_src.fits images are now _bmet.fits) Proc #8 (cropout) can now crop an image section by specifying its center and size in addition to its corners Added options to fixup and multi_fixup scripts that allow user customization Eliminated redundant configuration files Simplified setup process The IRACproc directory is now IRACproc/ #----------------------------------------------------------------------------- # New for v3.2.1 #----------------------------------------------------------------------------- Fixed bug in coadd_bcd that truncated WCS header keywords #----------------------------------------------------------------------------- # New for v3.2 #----------------------------------------------------------------------------- Outlier rejection improved for moderate coverage (4-24 frames) Latest Pmasks from the SSC are included (including Sub-Array) A master Fiducial Image Frame can be created for all channels The number of files that can be processed has been increased Proc #1 (fixup) can now group one or more related AORs into one directory for processing, multi_fixup will run fixup in batch mode Proc #6 (mksrcmap) now has parameter "scale" for fine tuning outlier rejection Proc #8 (cropout) is now done in PDL (vs. IRAF for previous versions) and has more functionality Update for coadd_bcd: multiple PSF subtraction now uses 'diff' function, etc. The _expmap.fits images are now simply the coverage maps for each mosaic (_mosaic_cov.fits) The measure/ and PSFsub/ directories have been replaced with analysis/ The useless/ directory has been replaced with .iracproc_tmp/ The contents of IRAC_proc/config/ are now copied to <SRC>/Lists/ so that copies of the configuration files are modified by the user IRAC_proc is now distributed independently from the HDR PSFs PSFs are available as IRAC_psfs-<VER>.tgz (PSFs have new file names) Go into IRAC_proc/ and untar #----------------------------------------------------------------------------- # New for v3.1 #----------------------------------------------------------------------------- IRAC_proc will now run on any standard RedHat Linux system with PDL, PGPlot, MOPEX, and IRAF/STSDAS installed IRACproc can now be installed anywhere on your linux system Simplified installation The IRAC_proc directory no longer contains the version number Bug fix and update for coadd_bcd The outputs from Processing steps #1-8 are unchanged from IRAC_proc_2.0 #----------------------------------------------------------------------------- # New for v3.0 #----------------------------------------------------------------------------- PSFs and PSF subtraction software Notes on how to handle Sub-Array data Improved documentation The outputs from Processing steps #1-8 are unchanged from IRAC_proc_2.0 Processing is more user friendly The number of files that can be processed has been increased #----------------------------------------------------------------------------- # New for v2.0 #----------------------------------------------------------------------------- Mosaic can now be made as large as MOPEX can handle Slightly improved outlier rejection Each channel can be processed independently Alternative provided to visually inspecting each BCD frame before processing Source maps (_srcmap.fits) and matched source maps (_matchsrc.fits) for each mosaic are no longer produced Copies each mosaic are no longer placed in <SRC>/
