susac [options] [\-b or \-j] ra dec
.SH Description
.I 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.
.SH Options
.B \-a
list single closest catalog source
.B \-b <RA> <Dec>
Output B1950 (FK4) coordinates around this center
.B \-d
Sort by distance from center instead of flux
.B \-h
Print heading, else do not
.B \-j <RA> <Dec>
Output J2000 (FK5) coordinates around this center
.B \-m [<bright magnitude>] <faint magnitude>
Limiting catalog magnitude(s) (default none, bright \-2 if only faint is given)
.B \-n <num>
Number of brightest stars to print
.B \-o <name>
Object name used to name output file
.B \-r <radius>
Search radius in arcsec (default 10)
.B \-s
Sort by right ascension instead of flux
.B \-t
Tab table to standard output as well as file
.B \-u <num>
Plate number for catalog sources (0=all)
.B \-v
