Notes.
Coefficients of the polynomials obtained by ODR fitting of the profile effective radius (in log) versus magnitude, for a sample of EFIGI galaxies defined by their morphological types, in the listed band. Bulge (or Sérsic) and disk (or exponential) refer to the corresponding component in the bulge and disk decomposition. When indicated, E, cD, dE and Im galaxies are modeled as single Sérsic profiles (see Sect. 3.1).
Coefficients of the polynomials providing the rms dispersion (in dex) around the size–magnitude relation fit.
The center and χ2 of the Gaussian fit to the residuals of the elliptical size–luminosity relation appear in the descriptive text in Sect. 4.2.
