Distribution of χ² of ZPEG best-fit PEGASE.2 template with the EFIGI NUVgri photometry (or only gri when NUV is not available) for whole galaxies compared with the χ² obtained with the gri only photometry of the bulge and disk components extracted with SourceXtractor++ by bulge+disk modeling. The 1 to 3 order of magnitude lower χ² for the bulges compared those for the whole galaxies, and the factor of 2−3 higher for disks validate the use of templates designed for whole galaxies.
