Notes.
Coefficients of the linear polynomials obtained by ODR fitting of the profile effective radius (in log) versus B/T (in log), for a sample of EFIGI galaxies defined by their morphological type, in the listed band. Bulge (or Sérsic) and disk (or exponential) refer to the corresponding component in the bulge and disk decomposition.
The center and χ2 of the Gaussian fits to the residuals of the bulge and disk effective radius versus B/T relations appear in the descriptive text in Sect. 4.7.3.
