1996ApJS..104..199W A MEDIUM-DEEP SURVEY OF A MINISLICE AT THE NORTH GALACTIC POLE. II. THE DATA C. N. A. WILLMER CNRS, Institut d'Astrophysique de Paris, 98 bis, Boulevard Arago, F-750 14, Paris, France DAVID C. KOO AND NANCY ELLMAN UCO/Lick Observatory and Board of Studies in Astronomy and Astrophysics, University of California, Santa Cruz, CA 95064 MICHAEL J. KURTZ Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138 AND ALEX S. SZALAY Department of Physics, Johns Hopkins University, Baltimore, MD 21218 Received 1995 June 30, accepted 1995 October 2 ABSTRACT We report 328 redshifts, b_J_ magnitudes, and b_J_ - r_F_ colors of galaxies measured in a redshift survey of a 4^deg^ x 0.67^deg^ slice close to the north Galactic pole. The faintest galaxies in this survey have a magnitude of b_j_ ~ 20.5. The redshifts present external errors of the order of 70 km s^-1^ and we estimate that the mean photometry errors are ~0.2 for magnitudes and ~0.3 for colors. The redshift completeness level of the sample is of the order of ~35% at b_J_ = 20, and part of this rather low completeness is the result of the combination of limitations imposed by the multifiber system with the clustering of galaxies, and an insufficient number of configurations. At the nominal magnitude limit of the survey, we were able to measure redshifts for ~70% of the galaxies we observed. From the correlation between observed properties of the galaxies in this sample, we demonstrate that the mean surface brightness is a major limiting factor in our ability to measure redshifts of faint objects.

II. The Data" by C. N. A. Willmer, David C. Koo, Nancy Ellman, Michael J. Kurtz, & Alex S. Szalay (ApJS, 104,199 [1996]), the equatorial coordinates of objects in Table 3 present a systematic error. A revision of Table 3 with the correct coordinates is presented here. The authors thank Marion Schmitz for pointing out the error. See Journal.
