Description:
The Guide Star Photometric Catalog (GSPC) is an all-sky set of 1477
photoelectrically determined BV sequences covering the magnitude range
from 9 to 15. The GSPC was created to provide photometric calibrators
for the HST Guide Star Catalog (GSC). Each sequence nominally contains
(at least) six stars, each with a photometric precision of 0.05 mag.
In practice, a small number of sequences contain fewer stars; and the
precisions achieved for the faintest stars are more nearly 0.1 mag.
For declinations greater than +3 degrees the sequences generally lie
near the centers of the original Palomar Observatory - National
Geographic Society Sky Atlas. Other sequences lie near the centers of
the ESO/SERC Southern Sky Atlas.
The catalog also includes a list of suspected variable stars, a
bibliography of literature sequences, and additional information which
was useful in the data reduction and for quality control of the final
catalog.
The full catalog is made of 7 FITS files: tables 1 to 5, references
(table 6 of the paper) and the actual catalogue (table 7 of the
paper). The ascii versions of Tables 1 to 5 are included in this file;
the ascii version of the references (refs.dat) and of the actual
catalogue (catalog.dat) are described here.
The updated version 1 was created by replacing photometric sequences
P040, P421, S335 and S742 in GSPC version 1. The updated sequences
have improved photometry and/or positions. In addition the sigma's in
V and B-V (here e_V and e_B-V) were replaced with the values provided
by the authors when we noted a discrepancy with the published values.

Description of the Catalog:
The catalog is available both as ASCII tables as well as FITS files,
and originally appeared on the ADC CD-ROM, Vol. 1.
