Can I use Bandmerge to combine tables of Spitzer photometry with photometry from other catalogs?

Yes, but it has to be in the same format as the Spitzer ASCII tables before you can do that. The only exception is 2MASS data, which can be read directly by Bandmerge if you set the project flag to 2 (1 is the default and applies to Spitzer data). For example,

bandmerge -i /data/ch1.tbl /data/ch2.tbl -p 2 -o output/
