Abstract:
We present an analysis of CCD images (obtained at the Palomar 1.5m
telescope) 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 deep 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.
