Notes. The first column gives the galaxy’s identification number in the MaNGA survey. The right ascension (RA) and declination (Dec) (J2000.0) of each galaxy are given in columns 2 and 3. The adopted distance is reported in column 4. The isophotal radius in arcmin and in kpc are listed in columns 5 and 6, respectively. The luminosity and the central surface brightness of the disc (reduced to the face-on) in the B band estimated here are given in columns 7 and 8. The central oxygen abundance and the radial abundance gradient estimated using the R calibration are reported in columns 9 and 10. Column 11 gives the value of the mean scatter around the O/H–Rg relation.
