Abstract:
We publish 1653 CCD photometric sequences in the Johnson-Kron-Cousins
standard system, distributed both in the northern and southern
hemispheres, useful for the calibration of photographic photometry of
Schmidt survey plates. The collection and reduction of the CCD data
presented here are part of a long-term program devoted to the
construction of the Second Guide Star Photometric Catalog (GSPC-II).
The GSPC-II is an all-sky catalog of photometric stellar sequences
with a limiting magnitude of V=19 or fainter, in the (B), V, and R
passbands of the Johnson-Kron-Cousins system. Standard photometric
errors are at the level of 0.07 for a V 19 magnitude star. These
sequences are being used by teams of the Space Telescope Science
Institute (STScI) and the Osservatorio Astronomico of Torino (OATo)
for the photometric calibration of the Second Guide Star Catalog.
Description:
The GSPC-II completes the Guide Star Photometric Catalog (Cat. II/143)
with stars between 14-19th magnitude near the center of each of the
Palomar and UKSTU survey fields. These were all observed using CCD
detectors from a number of different observatories.
