Shaded histograms show the distribution of SDSS Petrosian magnitudes for EFIGI galaxies in the u, g, r, i and z bands in intervals of 0.5 mag (2 upper left panels, and bottom panels), and the distribution of the PGC B_T magnitude for the 1006 EFIGI galaxies for which it is available (upper right panel). In each panel, the black lines shows the histograms restricted to galaxies of types Sd and later. All panels for SDSS magnitudes show an extension to faint magnitudes (enhanced by the logarithmic scale), caused by the limitations in the processing of large objects by the SDSS photometric pipeline.
