摘要：

We present an analysis of CCD images of more than 100 quasars; many of the objects have been or will be observed in the HST Key Project Quasar Absorption-Line Survey. The data set consists of B, g, and i photometry of 117 quasars and deeper g (limiting magnitude of almost-equal-to 22) images of 101 quasar fields. Positions accurate to almost-equal-to 1'', measured with the Space Telescope Science Institute's Astrometric Support Program, are listed for all of the quasars in this study. Positions, magnitudes, and classifications of stars and galaxies located within almost-equal-to 100'' of the quasars are given for all of the deep g data. The positions of the stars and galaxies relative to the quasar are accurate to almost-equal-to 0''5. The results presented here can be used to prepare spectroscopic programs designed to obtain redshifts of galaxies in the fields of these quasars.
