Scientific paper

Two-color (B - V and V - i) CCD photometry of the dominant galaxy (BCG) in five Bautz-Morgan type I clusters has been obtained at the 1.5 m Danish telescope at La Silla. In this paper, we analyze their surface brightness and color profiles. All galaxies but one have surface brightness profiles that can be described by a de Vaucouleurs' law with similar effective surface brightness mu(e) about 23.2 V mag/arcsec-squared and effective radius r(e) between 30 and 40 kpc. Average colors are alike in all the five galaxies and color gradients are small or absent.
