2MASS J01091553+3816258 , the SIMBAD biblio

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.
