Notes. Column 1: β-model; column 2: β parameter (assumed to be linked for the double β-model) ; column 3 (4): core radius of the first component, rc1, in arcmin (kpc); column 5 (6): core radius of the second component, rc2, in arcmin (kpc); column 7: normalization (see Eqs. (1) and (2)) ; column 8: ratio of the two components (see Eq. (2)); column 9: χ2/d.o.f.. The elliptical profile was extracted in annuli with PA = 33° and axis ratio (major/minor) = 1.5; the best-fit core radius is the value along the major axis.
