D.2 Bulge Profile

which characterizes the profiles of elliptical galaxies and bulge components of disk galaxies. According to this profile, the total brightness can be written as

while the central surface brightness and the average surface brightness inside the effective radius are related to by

(D.7) |

Remembering Equation A.5, the bulge profile given by Equation D.5 can be put on a magnitude scale

while equalling Equations A.4 and D.6, one can express as function of and , obtaining
