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. from NASA Library (NASA LIB)of IDL routines http://idlastro.gsfc.nasa.gov/homepage.html |
