2005AJ....129..630B Multicolor Surface Photometry of Lenticular Galaxies. I. The Data Sudhanshu Barway, Y. D. Mayya, Ajit K. Kembhavi, and S. K. Pandey Abstract. We present multicolor surface and aperture photometry in the B, V, R, and K' bands for a sample of 34 lenticular galaxies from the Uppsala General Catalogue. From surface photometric analysis, we obtain radial profiles of surface brightness, colors, ellipticity, position angle, and the Fourier coefficients that describe the departure of isophotal shapes from a purely elliptical form; we find the presence of dust lanes, patches, and ringlike structure in several galaxies in the sample. We obtain total integrated magnitudes and colors and find that these are in good agreement with the values from the Third Reference Catalogue. Isophotal colors are correlated with each other, following the sequence expected for early-type galaxies. The color gradients in lenticular galaxies are more negative than the corresponding gradients in elliptical galaxies. There is a good correlation between B-V and B-R color gradients, and the mean gradients in the B-V, B-R, and V-K'' colors are -0.13+/-0.06, -0.18+/-0.06, and -0.25+/-0.11 mag dex^-1^ in radius, respectively.
