Guide Star Catalog
(GSC, HSTGC, Hubble Space Telescope Guide Catalog)
(catalog of stars to help aim HST)
The Guide Star Catalog (GSC
or Hubble Space Telescope Guide Catalog or HSTGC)
is a catalog of stars compiled for use with
the Hubble Space Telescope, as guide stars, recognizable stars with
locations, to be used when refining the
aim at objects near these stars in the celestial sphere.
To make the catalog so-usable for accurate aiming,
it favors stars over other astronomical objects,
and favors non-binary stars.
GSC-I has 20 million stars of magnitudes +6
through +15, and GSC-II (aka GSC2) has nearly a billion
to magnitude +21.
The Guide Star Photometric Catalog (GSPC) is a catalog
including calibrated photometry of a smaller set
(fewer than 2000) of stars. Two major editions have been
produced, GSPC-I and GSPC-II.
