We present the techniques used to determine redshifts and to characterize the spectra of objects in the Caltech Faint Galaxy Redshift Survey in terms of spectral classes and redshift quality classes. These are then applied to spectra from an investigation of a complete sample of objects with K_s < 20 mag in a 2 × 7.3 arcmin^2 field at J005325+1234. Redshifts were successfully obtained for 163 of the 195 objects in the sample; these redshifts lie in the range [0.173, 1.44] and have a median of 0.58 (excluding 24 Galactic stars). The sample includes two broad-lined AGNs and one QSO.

Additional Information:© 1999 The American Astronomical Society. Received 1998 June 11; accepted 1998 September 17. Based in large part on observations obtained at the W. M. Keck Observatory, which is operated jointly by the California Institute of Technology and the University of California. The entire Keck/LRIS user community owes a huge debt to Jerry Nelson, Gerry Smith, Bev Oke, and many other people who have worked to make the Keck Telescope and LRIS a reality. We are grateful to the W. M. Keck Foundation, and particularly its late president, Howard Keck, for the vision to fund the construction of the W. M. Keck Observatory. J. G. C. is grateful for partial support from STScI/NASA grant AR-06337.12-94A. K. R. was supported in part by a Summer Undergraduate Research Fellowship at Caltech. R. D. B. acknowledges support under NSF grant AST95-29170. D. W. H. and M. A. P. were supported in part by Hubble Fellowship grants HF-01093.01-97A and HF-01099.01-97A from STScI (which is operated by AURA under NASA contract NAS5-26555).
