Abstract

We performed a BVR photometric survey for the entire Small Magellanic Cloud (~26 deg2) with a mosaicsystem, Wide Field Imager (WFI), covering three seasons: September and October 2001 and November 2002. Through theusual data reduction procedures, we present ~0.73 million catalogue stars brighter than 19 magnitude in B amongst a totalof ~1 3 million and compare them with published astrometry and photometry results. We found that the averagedifferences between our and the published data are ~0.7 arcsec in astrometry and 0.065, 0.054, and 0.163 in B, V, and R,respectively, in photometry. In addition, using the 2dF spectroscopic data from Evans et al. (2004), we determined thecolor excesses in (B V) and (V R) to be 0.086±0.156, and 0.065±0.112, respectively, while for the distance modulus, weobtained 18.55±1.05.
