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 < 0 .17\" are unreliable, especially for galaxies with a steep light profile)\\n    2.
