We present deep optical imaging observations of 2 square degree area, covered by the Cosmic Evolution Survey ( COSMOS), made by the prime-focus camera ( Supreme-Cam) on the 8.2 m Subaru Telescope. Observations were done in six broadband [B ( 4459.7 angstrom), g' ( 4723.1 angstrom), V ( 5483.8 angstrom), r' ( 6213.0 angstrom), i' (7640.8 angstrom), z' ( 8855.0 angstrom)] and one narrowband ( NB816) filters. A total of 10(6) galaxies were detected to i'similar to 26.5 mag. These data, combined with observations at u* and K- band are used to construct the photometric catalogs for the COSMOS, to measure their photometric redshifts, multiband spectral energy distributions, and stellar masses, and to identify high-redshift candidates. This catalog provides multi-wave band data for scientific analysis of the COSMOS survey.

Abstract
We present deep optical imaging observations of 2 square degree area, covered by the Cosmic Evolution Survey ( COSMOS), made by the prime-focus camera ( Supreme-Cam) on the 8.2 m Subaru Telescope. Observations were done in six broadband [B ( 4459.7 angstrom), g' ( 4723.1 angstrom), V ( 5483.8 angstrom), r' ( 6213.0 angstrom), i' (7640.8 angstrom), z' ( 8855.0 angstrom)] and one narrowband ( NB816) filters. A total of 10(6) galaxies were detected to i'similar to 26.5 mag. These data, combined with observations at u* and K- band are used to construct the photometric catalogs for the COSMOS, to measure their photometric redshifts, multiband spectral energy distributions, and stellar masses, and to identify high-redshift candidates. This catalog provides multi-wave band data for scientific analysis of the COSMOS survey.
