Notes. The “type” in the first column is the joint probability that a galaxy is elliptical and lenticular (pE + pS0) (i.e., that the galaxy is an early-type object); the cut-off value is early-type = pE + pS0 ≥ 0.5. The total number of galaxies in the table is 2169 for the sample based on the empirical library and 2055 for the sample based on the synthetic library because the galaxies for which both h3 and h4 parameters could not be determined accurately were not included.
