Description:
CCD photometric standard stars in the BVRc system of Johnson and
Cousins are presented for two regions of importance in studies of
galactic structure and kinematics: the North galactic pole (NGP), and
a second galactic plane region (GPR) toward the anticenter. Precision
and accuracy are better than 0.05mag down to V=18-18.5.
These data are part of the Second Guide Photometric Catalog (GSPC-II).

Note (1): The format of the CCD identifier is nnn-N, where nnn is a
progressive index, while N = I,II,III identifies three different
close CCD fields.

Historical Notes:
CCD data were taken at Mt. Hopkins using the 1.2m telescope.
The GPR (table4) was observed on October 15 1993, while
the NGP fields (table3) were imaged on June 5 1994.
