=========================================================================== COSMOS Subaru Data =========================================================================== The Cosmic Evolution Survey (COSMOS) is an HST Treasury Project to survey a 2 square degree equatorial field, centered on RA=10:00:28.6 and DEC=+02:12:21.0, using the ACS camera. The project also incorporates major commitments from other observatories around the world, including the VLA radio telescope, ESO's VLT in Chile, ESA's XMM X-ray satellite, and the Japanese 8-meter Subaru telescope in Hawaii. These images are scattered light corrected flat fields for the Subaru Suprime-Cam camera used for the COSMOS data reduction, see Capak et. al. (2007) for details. They were generated between Jan, 2004 and Feb, 2005 (see Tanaguchi et. al. (2007) for the exact dates). The flats appear stable at the 1% level across multiple runs during this observing period. The chips have been re-numbered and the overscan region has been removed from the raw data. As a result, there is a positional offset and name change between the raw Suprime-Cam data and these frames; these are given at the end of this file. All chips are normalized to a median of 1; Chip-to-Chip sensitivity variations are given at the end of this file.
