We present deep optical imaging observations of 2 square degree area, coveredby the Cosmic Evolution Survey (COSMOS), made by the prime-focus Camera(Supreme-Cam) on the 8.2m Subaru Telescope. Observations were done in sixbroad-band [B (4459.7 AA), g' (4723.1 AA), V (5483.8 AA), r' (6213.0 AA), i'(7640.8 AA), z' (8855.0 AA)], and one narrow-band (NB816) filters. A total of10^6 galaxies were detected to i'~26.5 mag. These data, combined withobservations at u* and K-band are used to construct the photometric catalogsfor the COSMOS and to measure their photometric redshifts, multi-band spectralenergy distributions, stellar masses and identification of high redshiftcandidates. This catalog provides multi-waveband data for scientific analysisof the COSMOS survey.Comment: 46 pages, 32 figures, accepted for the COSMOS special issue of ApJ
