COSMOS2015 Catalog

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.
