Synopsis

Description

12       sgsc  is  a utility for finding all of the Hubble Space Telescope Guide
13       Star Catalog objects in a specified region of the sky and listing  them
14       with  their  sky  positions and magnitudes in order of brightness, with
15       the brighter ones first.  Output is to standard out, unless the -w flag
16       is  set,  in  which case it goes to objectname.gsc or search.gsc. It is
17       somewhat similar to RGSC, which can search from  lists  of  coordinates
18       but cannot sort the output.  It is a link to scat.
