VizieR Online Data Catalog: Isophotal shapes of early-type galaxies (Chaware+, 2014)
Abstract
The imaging data were originally obtained as part of a faint quasar survey using the Large Format Camera (LFC) on the 5 m Hale Telescope at Mount Palomar Observatory, with integrated exposures ranging from 1 to 4 hr in r, i, and z filters. The LFC is a mosaic of six 2048x4096 pixel CCDs, mounted at the prime focus of the Hale Telescope. The fields targeted were those of known SDSS high-redshift (z>5) quasars in order to look for a local over-density of quasars (Mahabal et al. 2005ApJ...634L...9M). We obtained reduced images, which were bias subtracted, flat fielded, and processed to remove cosmic rays as a part of the original program. The deep LFC images have excellent signal-to-noise ratio (S/N), permitting us to examine faint features, including the outermost extensions of the galaxies, down to ~0.1% of the sky brightness.
