Abstract
Possible surface brightness selection effects in the redshift catalogs of the Canada-France Redshift Survey are investigated through compari sons of subsamples of the data. Our analyses demonstrate that the secu ring of redshifts is independent of possible biases arising from surfa ce brightness effects and/or differing galaxy morphologies and orienta tions. The unusual geometry of the mask designs for our spectroscopic observations also do not produce any significant bias. There is, howev er, a bias at the highest and lowest redshifts, especially for absorpt ion-line galaxies at z > 1 and z < 0.2, due to the adopted spectral ra nge (4250-8500 Angstrom). Apart from the latter, we conclude that our sample of identified galaxies is an unbiased subsample of the original photometric catalog and is essentially limited by I-band flux density (17.5 less than or equal to I-AB less than or equal to 22.5). Finally , spectroscopic data for the remaining CFRS field is presented. Data f or 273 objects in the 0300+0000 held are given.
