Abstract

Ground-based counts and colours of faint galaxies in the U and R bands in one field at high Galactic latitude are presented. Integrated over flux, a total of 1.2 × 10^5 source deg^(−2) are found to U = 25.5 mag and 6.3 × 10^5 source deg^(−2) to R = 27 mag, with d log N/dm ∼ 0.5 in the U band and d log N/dm ∼ 0.3 in the R band. Consistent with these number-magnitude curves, sources become bluer with increasing magnitude to median U— R= 0.6 mag at 24

Keck Observatory. We benefited from helpful conversations with Kurt Adelberger, John Gizis, Tomislav Kundic, Gerry Neugebauer, Sterl Phinney and Chuck Steidel, and from comments from an anonymous referee. We are grateful for financial support from NSF grant AST 92-23370 (DWH, RB), NSF grant AST-91-57412 and the Bressler Foundation (MAP), support through a PPARC Advanced Fellowship (IS), and grants from NSF and NASA (BTS). The calibrated images used for this investigation will be made available to the public; contact the authors for more information. This work is based on observations obtained at the W. M. Keck Observatory, which is operated jointly by the California Institute of Technology and the University of California; and at the Palomar Observatory, which is owned and operated by the California Institute of Technology.
