It contains an extensive compilation of information on almost 300000 stars. 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.
