Howell-Everett UBV Photometric Survey of the Kepler Field ("KPLRUBV")

The Howell-Everett Kepler Field UBV Survey contains a list of 4,414,002 sources observed in a survey of the NASA Kepler Mission field using Johnson/Harris U, B, and V filters in the NOAO Mosaic1.1 Camera at the WIYN 0.9m Telescope on Kitt Peak. The survey data were taken from 206 slightly-overlapping pointings that cover 191 square degrees in each of the three passbands. The area covered includes almost the entire Kepler field plus areas between the Kepler CCDs and around the perimeter of the field. The survey is estimated to be complete to magnitudes as faint as U~18.7, B~19.3, and V~19.1, but varies with location. The mean bright limits for point sources are U=10.1, B=10.6 and V=10.5.
