Notes. O/H is the central oxygen abundance 12 + log(O/H)0 (Col. 2), the oxygen abundances at the optical radius 12 + log(O/H)R25 (Col. 3), and at the galaxy effective radius 12 + log(O/H)Re, g (Col. 4). X is the rotation velocity Vrot (row 1), the stellar mass Mma (row 2), the luminosity LB (row 3), the optical radius R25 (row 4), the stellar mass Msp (row 5), and the parameters Msp/Re, g and Msp/
(rows 6 and 7). The diagrams are shown in Figs. 19–21. The scatter relative to the mean values in bins is given.
