Notes. (1) Central SB in cts/s/arcmin2; (2) slope β1; (3) core radius 1 in kpc; (4) reduced χ2; (5)–(7) correspond to the second model component: central SB; slope β2 and core radius 2, respectively. Errors are not presented when the parameter value is at the limit imposed by the fitting procedure.
