The HST Quasar Absorption Line Key Project VIII. CCD Imaging of Hubble Space Telescope Quasar Fields
Abstract
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 ~22) images of 101 quasar fields. Positions accurate 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 ~100" of the quasars are given for all of the dep g data. The positions of the stars and galaxies relative to the quasar are accurate 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. (SECTION: Quasars and Active Galactic Nuclei)
