Abstract
We publish 622 CCD photometric sequences in the Johnson-Kron-Cousins standa rd system, distributed both in the northern and southern hemispheres, usefu l for the calibration of photographic photometry of Schmidt survey plates. The collection and reduction of the CCD data presented here are part of a l ong-term program devoted to the construction of the Second Guide Star Photo metric 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 photomet ric errors are at the level of similar to0.07 for a V similar to 19 magnitu de star. These sequences are being used by teams of the Space Telescope Sci ence Institute (STScI) and the Osservatorio Astronomico of Torino (OATo) fo r the photometric calibration of the Second Guide Star Catalog.
