Notes on Swarped images:

For plckg004-19, the footprint in ch1 and ch2 are different enough so that 
MOPEX was unable to drizzle both channels on the same pixel grid. So I ran 
Swarp on both channels to resample them onto the same pixel grid. These are 
the files with "swp" in their names. The images without "swp" are the original 
output mosaic from MOPEX.
