The Guide Star Catalog is an online catalogue of stars produced for the purpose of accurately positioning and identifying stars satisfactory for use as guide stars by the Hubble Space Telescope program. The first version of the catalogue was produced in the late 1980s by digitizing photographic plates and contained about 20 million stars, out ...
GRO — Gamma Ray Observatory (NASA — Compton) Groombridge (Stephen Groombridge, 1755–1832) GSC — Guide Star Catalog. GSC2 / GSC II — Guide Star Catalog II; GSPC — Guide Star Photometric Catalog. GSPC2 — Guide Star Photometric Catalog, 2nd; Gsh — J. Glaisher (double stars) GΣ — G. Struve (double stars) Gtb — K. Gottlieb ...
The NASA Star and Exoplanet Database (NStED) is an on-line astronomical stellar and exoplanet catalog and data service that collates and cross-correlates astronomical data and information on exoplanets and their host stars.
In contrast to the PPM, these older catalogs are based on (1) the now obsolete FK4 system of positions and proper motions, and (2) only two position measures per star. [2] While the SAO catalog is more or less complete to V=9, with 4,503 stars fainter than V=10, the PPM catalog is fairly complete to V=9.5, with 102,672 stars fainter than V=10 ...
The term Digitized Sky Survey originally referred to the publication in 1994 of a digital version of an all-sky photographic atlas used to produce the first version of the Guide Star Catalog.
The Tycho Input Catalog was created by the Hipparcos/Tycho international consortia in preparation for the Hipparcos satellite mission. They produced a catalog containing the best available data for all stars to magnitude 11. Adding the bright star data from this catalog to the GSC produced a complete all-sky catalog down to the GSC limiting ...
Sir Patrick Moore compiled the Caldwell catalogue in 1995 to complement the Messier catalog, listing 109 bright star clusters, nebulae, and galaxies named C1 to C109. This is a list of deep-sky objects of interest to amateur astronomy and not a catalog in the professional science sense. Other deep-sky observing lists for amateur astronomers ...
Online version of the SAO Catalog was created by the HEASARC in March 2001 based on ADC/CDS Catalog I/131A, which itself is originally derived from a character-coded machine-readable version of the Smithsonian Astrophysical Observatory Star Catalog (SAO, SAO Staff 1966) prepared by T.A. Nagy in 1979, and subsequently modified over the next ...
