Description:
   The SKYMAP Star Catalog System consists of a Master Catalog stellar
   database and a collection of utility software designed to create and
   maintain the database and to generate derivative mission star catalogs
   (run catalogs). It contains an extensive compilation of information on
   almost 300000 stars brighter than 8.0 mag.

Introduction:
   The original SKYMAP Master Catalog was generated in the early 1970's.
   Incremental updates and corrections were made over the following years
   but the first complete revision of the source data occurred with Version
   4.0. This revision also produced a unique, consolidated source of
   astrometric information which can be used by the astronomical community.
   The derived quantities were removed and wideband and photometric data in
   the R (red) and I (infrared) systems were added. This version, the most
   recent, is discussed in detail in sky.txt.

   Confer.txt describes these upgrades in detail. There are some
   deficiencies that exist in the SKY2000 Master Catalog that we are aware
   of. These items will be researched and corrected in future SKY2000
   Master Catalog releases. (See deficient.txt).
