Beginning of ReadMe : I/254 The HST Guide Star Catalog, Version 1.2 (Lasker+ 1996) ================================================================================ The Guide Star Catalog Version 1.2: an astrometric recalibration and other refinements. Morrison J.E., Roeser S., McLean B., Bucciarelli B., Lasker B. <Astron. J., 121, 1752 (2001)> =2001AJ....121.1752M ================================================================================ ADC_Keywords: Surveys ; Positional data Description: The Guide Star Catalog (GSC), which has been constructed to support the operational need of the Hubble Space Telescope contains nearly 19 million objects brighter than sixteenth magnitude, of which more than 15 million are classified as stars. This catalog provides positions and magnitudes for these stars. The original version of this catalog, GSC 1.0, is described in a series of papers: Lasker et al. (1990AJ.....99.2019L); Russell et al. (1990AJ.....99.2059R); and Jenkner et al. (1990AJ.....99.2082J) The reference material for the GSC 1.2 reduction is the "Positions and Proper Motions Catalogue": PPM-North, Roeser S. and Bastian U., 1988, Cat. I/146 PPM-South, Bastian U. and Roeser S., 1993, Cat. I/193 PPM-Suppl, Roeser S., Bastian U. and Kuzmin A., 1994, Cat. I/208 and the Astrographic Catalogue (AC) which was used to remove the mean systematics common to all the plates. The overall rms error of the GSC 1.2 is estimated better than 0.3arcsec The STScI provides the details of the GSC versions ("See also" section below) A binary version of the GSC1.2, with C code for querying, is available in the subdirectory GSC.
