This is a bash script that uses the script cdfpmatI to combine the contents of usno.cdfp, 2mass.cdfp, and sdss.cdfp into a single catalog named STARS.cdfp, the fundamental source of calibration data for many of the WCS tasks.
Sample Usage: % catalog_combineIt is useful to note that this bash script uses the bc unix task to perform shell arithemtic and does some of my earliest in-shell numerical tasks. It may change in the future, but many of these features will remain, and hence, this will serve as a nice template shell.
