4.4 Internal Comparison of Photometry

Since almost half of the galaxies have been observed more than once in Gunn r and Johnson B (cf. Table [*], p. [*]), we have ample opportunity to determine the internal accuracy of the data. For the photometry, we first compare aperture magnitudes, and then the entire surface brightness profiles.
