I/254/out The HST Guide Star Catalog, Version 1.2 (Lasker+ 1996)
The Full Catalogue (25241730 positions) (25241730 rows)
  GSC=0863300394
Post annotation about this record

Note: The Guide Star Catalog has been constructed to support the operational need of the Hubble Space Telescope. It contains over 25 million positions for about 19 million objects, of which more than 15 million are classified as stars. The version 1.2 is a new astrometric reduction which results in absolute position errors about 0.3-0.4 arcsec. (see GSC pages at URL http://www-gsss.stsci.edu/gsc/gsc.html)
