Abstract (from CDS):

We present the COSMOS201524 catalog, which contains precise photometric redshifts and stellar masses for more than half a million objects over the 2deg2 COSMOS field. Including new {{YJHK}}_{s} images from the UltraVISTA-DR2 survey, Y-band images from Subaru/Hyper-Suprime-Cam, and infrared data from the Spitzer Large Area Survey with the Hyper-Suprime-Cam Spitzer legacy program, this near-infrared-selected catalog is highly optimized for the study of galaxy evolution and environments in the early universe. To maximize catalog completeness for bluer objects and at higher redshifts, objects have been detected on a χ 2 sum of the {{YJHK}}_{s} and z ++ images. The catalog contains ∼6×{10}^{5} objects in the 1.5 deg2 UltraVISTA-DR2 region and ∼1.5×{10}^{5} objects are detected in the "ultra-deep stripes" (0.62 deg2) at {K}_{s}\leqslant 24.7 (3σ, 3'', AB magnitude). Through a comparison with the zCOSMOS-bright spectroscopic redshifts, we measure a photometric redshift precision of σ_{Δz/(1+{z}_{s})} =0.007 and a catastrophic failure fraction of η = 0.5 %. At 3\lt z\lt 6 , using the unique database of spectroscopic redshifts in COSMOS, we find σ_{Δz/(1+{z}_{s})} =0.021 and η = 13.2 % . The deepest regions reach a 90% completeness limit of {10}^{10}{M}_☉ to z=4. Detailed comparisons of the color distributions, number counts, and clustering show excellent agreement with the literature in the same mass ranges. COSMOS2015 represents a unique, publicly available, valuable resource with which to investigate the evolution of galaxies within their environment back to the earliest stages of the history of the universe. The COSMOS2015 catalog is distributed via anonymous ftp and through the usual astronomical archive systems (CDS, ESO Phase 3, IRSA).

sedIcon
within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
