<br/><br/> In this MSc study, we aim to determine the shape of the surface brightness profile of the extended envelope of a sample of cD galaxies. Both de Vaucouleurs r1/4 low and Sersic's r1/n model, on  their own, provide a poor description of the surface brightness profiles of cD galaxies. We therefore plan to determine the most  appropriate analytical model to describe cD galaxy, whether this be  an exponential profile, a Sersic model, or some other function. We additionally intend to measure the fraction of light contained within their different components. Among others the following will be  determined: Luminosity profiles along the major and minor axes, Structural profiles (Position angle profile, ellipticity profile, etc.),  Color distribution
