UBVI Surface Photometry of the Spiral Galaxy NGC 300 in the Sculptor Group

We present UB Visurface photometry over a 20.5'× 20.5' area of the latetype spiral galaxy NGC 300.We have derived isophotal maps,surface brightness profiles,ellipticity profiles,position angle profiles,and color profiles.By merging ourI-band measurements with those of Boker et al.Based on Hubble Space Telescope observations,we have obtained combinedI-band surface brightness profiles for the region 0.02″＜ r ＜ 500″ and have decomposed the profiles into three components:a nucleus,a bulge,and an exponential disk.
