Find USNO-SA2.0 Catalog stars in a square on the sky
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.
Options
-a list single closest catalog source
-b <RA> <Dec> Output B1950 (FK4) coordinates around this center
-d Sort by distance from center instead of flux
-h Print heading, else do not
-j <RA> <Dec> Output J2000 (FK5) coordinates around this center
-m [<bright magnitude>] <faint magnitude> Limiting catalog magnitude(s) (default none, bright -2 if only faint is given)
-n <num> Number of brightest stars to print
-o <name> Object name used to name output file
-r <radius> Search radius in arcsec (default 10)
-s Sort by right ascension instead of flux
-t Tab table to standard output as well as file
-u <num> Plate number for catalog sources (0=all)
-v Verbose listing of processing intermediate results
-w Write tab table output file imagename.uac
