COSMOS Zurich Structure & Morphology Catalog

The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra) and a number of large ground based telescopes (Subaru, VLA, ESO-VLT, UKIRT, NOAO, CFHT, and others). Over 2 million galaxies are detected, spanning 75% of the age of the universe.\n\nThis catalog contains the measurements presented in:\n\n 1.

Scarlata, Carollo, Lilly et al 2007, ApJS, 172, 406 (i.e., the Zurich Estimator of Structural Type [ZEST] catalog; measurements down to a limiting magnitude of I_AB=24. ZEST measurements for galaxies with half-light radii 22.5 - however, the quality of the fits deteriorates for sources substantially fainter than ~I_AB~23)\n\nThis v1.0 catalog is based on the May 2006 release of Alexie Leauthaud's ACS catalog (cut at the limits mentioned above).
