COSMOS is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structural environment. 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.
The COSMOS Cassata Morphology Catalog includes concentration, asymmetry, gini, and M20 measurements within the Petrosian radius. The morphological parameters are combined to classify galaxies as early-types, disks and irregulars.
The COSMOS2015 catalogue contains precise photometric red-shifts and stellar masses for more than half a million objects over the 2 deg^2 COSMOS field. Including YJHKs images from the UltraVISTA-DR2 survey, Y-band from Subaru/Hyper-Suprime-Cam and infrared data from SPLASH Spitzer Legacy program, this near-infrared selected catalogue is highly optimised for the study of galaxy evolution and environments in the early Universe.
In these catalogues, source detection and multi-wavelength photometry is performed for 1.7 million sources in the 2 square degree COSMOS field. Approximately 966,000 of these sources are measured with all available broad-band data using both traditional aperture photometry and a new profile-fitting photometric tool, The Farmer, developed by the COSMOS team. Photometric redshifts are computed for all sources in each catalogue using two independent photometric redshift codes, LePhare and EAZY. At i < 21, sources have sub-percent photometric redshift precision and even the faintest sources at 25 < i < 27 reach a photometric redshift accuracy of 5%.

The GMRT observations of the 2 sq. deg. COSMOS field were conducted using 30 antennas, their longest baseline being 25 km. The channel width of observations was 125 kHz, with a total bandwidth of 32 MHz.

Description:
COSMOS is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structural environment. 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.

This is an I band selected multi-color catalog for 2 square degrees centered on the COSMOS field at 10:00:28.6, +02:12:21. A detailed description of the catalog is given in Capak et. al. (2007) and it is recomended that you read this paper before using the catalog.

The COSMOS Tasca Morphology Catalog includes morphological parameters computed using Morpheus 2005. Morphological types are estimated in three different ways; for more details see Tasca et al. (2009).
