This compact version of the Guide Star Catalogue Version 1.1
(an all-sky astrometric and photometric catalog to support the operation 
of the Hubble Space Telescope, The Association of Universities for Research in
Astronomy, Inc. ([c] 1989, 1992)) was prepared by 
    A. Preite-Martinez and F. Ochsenbein, and presented as 
    "A Pocket version of the Guide Star Catalogue" in
    "Handling & Archiving Data from Ground-based Telescopes", Trieste 1993,
     ESO Conference and Workshop Proceedings No 50 (ISBN 3-923524-53-6),
     p. 199
================================================================================

This directory includes executables and binary indexes for fast queries.
The files are:

regions.bin, regions.ind : binary indexes of regions used by gsc.exe.

gsc.exe: query program which allows to retrieve the GSC stars in a
  small circle around a target position (or at a distance between two
  limits), or from a GSC-id identification (a number combining the region
  and star) with the -g option. This program has a lot of other options 
  summarized with the -help option.

  To have gsc.exe running properly, two environment variables are required:
  GSCDAT :    the name of the directory which contains the [NS]* subdirectories;
  GSCBIN :    the name of the directory which contains the binary indexes.
  The default setup of these variables are:
  GSCDAT=/GSC  on Unix       set GSCDAT=\GSC     on MS-DOS
  GSCBIN=$GSCDAT/bin         set GSCBIN=$GSCDAT\bin

  The usage of two variables allow to move only the binary files ($GSCBIN) 
  to a magnetic drive, leaving the bulk data ($GSCDAT) to a dedicated (e.g. 
  optical) drive.
  
decode.exe:
  allows to rebuild the original GSC files from the binary version.
  For instance, to recreate the 4615 region, execute
  decode.exe ../N8230/4615.GSC

Questions, comments, suggestions are welcome!
