Notes. α(J2000) and δ(J2000) are the equatorial coordinates of the galaxy centre; b/a is the ratio of minor to major axes; PA is the position angle of the major axis; (m − M)0 is the true distance modulus; A(F475W) and A(F814W) are the foreground extinction in corresponding passbands; MSTARS is the stellar mass; MH I is the mass of neutral hydrogen; M/LV is the lower limit of the mass-to-luminosity ratio; 12 + log(O/H) is the oxygen abundance; and <[Fe/H]> is the average metallicity.
