.le
.ls -m [<bright magnitude>] <faint magnitude>
Limiting catalog magnitude(s) (default none, bright -2 if only faint is given)
.le
.ls -n <num>
Number of brightest stars to print
.le
.ls -o <name>
Object name used for output file naming
.le
.ls -r <radius>
Radius of search circle 1in arcsec (default 10)
.le
.ls -s

DESCRIPTION
.I sgsc
is a utility for finding all of the GSC II
Catalog objects in a specified region of the sky and listing them with their
sky positions and magnitudes in order of brightness, with the brighter ones
first.
Output is to standard out, unless the -w flag is set, in
which case it goes to objectname.gsc2 or search.gsc2.
It is a link to scat.
