Details on how to run the the overlap and mosaic scripts:

When downloading data from leopard, be sure to download the calibration data in addition to the bcd data.

source /usr/beverly/spitzer/mopex/mopex_030106/mopex.csh [ use proper path ]

cd to the bcd directory

ls *bcd.fits > image_stack_all3.txt

ls *_bunc.fits > sigmalist_all3.txt

ls *_bbmsk.fits > dmasklist_all3.txt

edit all of the above files, remove *_0000_5_bcd.fits, etc, (or *_0000_3_bcd.fits) (these are the first exposures).

wc *txt ---> make sure these files are all the same size

Check to make sure all images are `prime' and that the integration times ok by using IRAF:

• ls *bcd.fits > junk2
• cl
• images
• imhead *bcd.fits l+ | match PRIMEARR > junk
• imhead *bcd.fits l+ | match DCENUM > junk7
• logout
• paste junk junk2 > junk3
• more junk3
• Check to see if any AREN'T prime: remove non-prime from all above files
• paste junk7 junk2 > junk8
• more junk8
• Remove all with DCENUM = 0

mkdir ../cal/

cp ../cal/*pmask.fits ../cal/pmask.fits

mkdir cdf

copy mosaic.ch3.nl.txt and overlap.ch3.nl.txt to the cdf subdirectory

overlap.pl -n overlap.ch3.nl.txt

NOTE: this creates files in overlap3/Overlap_Corr

mosaic.pl -n mosaic.ch3.nl.txt

NOTE: this puts an output file called mosaic.fits in mosaic3/Combine
