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.
