VizieR Online Data Catalog: COSMOS photometric redshift catalog (Ilbert+, 2009)

Compared with the previous optical/NIR catalog (Capak et al., 2007ApJS..172...99C, Cat. II/284), the new photometry implements 14 new medium/narrowband data from the Subaru Telescope, deep ground-based NIR data (J and K bands), and Spitzer-IRAC data. The spectroscopic sample used to calibrate/test the photo-z is 10 times larger at i⁺_AB<22.5 than that of Mobasher et al. (2007ApJS..172..117M). The spectroscopic sample is supplemented with faint IR selected sources and a deep, faint spectroscopic sample at z>1.5. Hereafter, we detail the photometric and spectroscopic data used to measure the photo-z.

Fluxes are measured in 30 bands from data taken on the Subaru (4200-9000Åg), CFHT (3900-21500Å), UKIRT (12500Å), Spitzer (3.6-8um), and GALEX (1500.2300Å) telescopes. We refer to P. Capak et al. (2008, in preparation) for a complete description of the observations, data reduction, and the photometry catalog.
