Dependences of the Sérsic index on the type (top panel) and the ratio of the Sérsic index in each Herschel band to the Sérsic index in the WISE W1 band on the type (bottom panel). The dependences are plotted for the averaged data for the subsample of 320 galaxies in each bin of 1 T with 15 and 85 percentiles shown. All lenticular galaxies (T ≤ 0) are combined together and shown by T = −2. Sm and Sdm galaxies are joined together in one type T = 8.
