- Description:
- 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%.

- 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.

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.

Morphological types are estimated in three different ways; for more details see Tasca et al. (2009).

Over 2 million galaxies are detected, spanning 75% of the age of the universe. These VLA data represent the additional 62 hrs of 1.4 GHz (20cm) observations of the central 7 pointings already imaged by the large project in A-configuration in February/March 2006. The observations have been combined with the large project in which the 2 square degree COSMOS field with the position given above as the center of the field was surveyed for 275 hours. The observations of the large project were performed at 1.4 GHz (20 cm), using the VLA in its A- and C-configuration between September 2004 and September 2005. The final combined survey has reached a sensitivity of an rms of uJy/beam in the central 30' at a resolution of 2.5"x2.5".

- Description:
- The catalog contains sources selected down to a 5 sigma (sigma~2.3 uJy/beam) threshold. This catalog can be used for statistical analyses, accompanied with the corrections given in the data & catalog release paper (Smolcic et al. 2016). All completeness & bias corrections and source counts presented in Smolcic et al. (2016) were calculated using this sample. The total fraction of spurious sources in the COSMOS 2 sq.deg. is below 2.7% within this catalog. However, an increase of spurious sources (up to 24% at 5.0<S/N<5.5) is present (for details see Sec. 5.2., Fig. 16 and Tab 3 in the data & catalog release paper). A subsample with a minimal spurious source fraction can be selected by requiring a signal-to-noise ratio SNR # 5.5 (see Sec. 5.2., Fig. 16 and Tab 3 in the data & catalog release paper). The total fraction of spurious sources in the COSMOS 2 sq.deg. within such a selected sample is below 0.4%, and the fraction of spurious sources is below 3% even at the lowest SNR (=5.5).
