The following PDF file documents our data
reduction procedures utilizing IRAF and IDL.
cormex.pdf


Additional IDL Routines

cormdiff.pro Converts two-planed (R1,R2)
CorMASS FITS file to a differenced image
(R2-R1) and writes to a working directory.

cormass2.pro Pre-processes CorMASS 'differenced' (R2-R1)
images to correct for reset voltage decay pattern
effects present in NICMOS3 images.

magicsub2.pro Used with cormass2.pro

numlines.pro
readfits.pro
writefits.pro
sxaddhist.pro
Used with cormdiff and/or cormass2.
