Difference between the DAP and our measurements of the gas velocity dispersion σ and the oxygen abundance O/H. Panel a1: the grey points show the difference dσ = σ_DAP–σ_our as a function of H_α flux for all the individual spaxels in seven galaxies. The red points show the mean values of the difference in bins of 0.2 dex in H_α flux. Panel a2: same as panel a1 but for the spaxels in the spots. Panel b1: the grey points show the difference d(O/H) = log(O/H)_DAP – log(O/H)_our as a function of H_α flux for all the individual spaxels. The red points show the mean values of difference in bins of 0.2 dex in H_α flux. Panel b2: same as panel b1 but for the spaxels in the spots.
