Synopsis
susac [options] [-b or -j] ra dec
Description
suac
finds all of the U.S. Naval Observatory SA2.0 Catalog objects in a specified
region of the sky and lists their sky positions and magnitudes in order of
brightness. Output is to standard out, unless the -w flag is set, in which
case it goes to objectname.uac or search.uac. It is a link to scat.
