J/PASP/106/646   HST quasar absorption-line key project. VIII. (Kirhakos+, 1994)

The HST quasar absorption-line key project. VIII. CCD imaging of Hubble Space Telescope quasar fields. Kirhakos S., Sargent W.L.W., Schneider D.P., Bahcall J.N., Jannuzi B.T., Maoz D., Small T.A. <Publ. Astron. Soc. Pac. 106, 646 (1994)> =1994PASP..106..646K
ADC_Keywords: QSOs ; Redshifts ; Photometry, CCD 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. File Summary:
