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

摘要

We present UB VI surface photometry over a 20.5′ x 20.5′ area of the late-type spiral galaxy NGC 300. We have derived isophotal maps, surface brightness profiles, ellipticity profiles, position angle profiles, and color profiles. By merging our I-band measurements with those of Boeker et al. based on Hubble Space Telescope observations, we have obtained combined I-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.
