Abstract:
Positions and magnitudes are given for 488 quasar candidates, 14 compact
emission-line galaxies, and eight white dwarf candidates discovered with
Canada-France-Hawaii blue grens in a 7.5 square degree area in the
directions 1338 + 27 and 1639 + 40. The goal of this survey is to enlarge
the areas previously surveyed in these regions to provide magnitude-limited
samples of quasars for the study of the luminosity function and large scale
distribution of quasars at moderate to high redshifts. Redshifts are given
for seven of the new quasars, including one BAL quasar.
Note: The explanations for last three columns are not clear in the
present paper, and those found in Crampton et al. 1985 (AJ, 90, 987)
p994 are adopted.
