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 ̊), g′ (4723.1 ̊), V (5483.8 ̊), r′ (6213.0 ̊), i′(7640.8 ̊),z′ (8855.0 ̊)] and one narrowband (NB816) filters. A total of 10 6 galaxies were detected to i′∼ 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.
