Comparison of the metallicity measurements of all spaxels in all galaxies of our sample for the two different metallicity diagnostics. Right: high-mass galaxies (log(M_⋆/M_⊙)≥9.3). Left: low-mass galaxies (log(M_⋆/M_⊙) < 9.3). In both plots, the behavior of star-forming (SF) and composite (Comp) spaxels can be seen in the top panels. Their relationship is modeled via a linear approach and a least square fit, where P04_12+log(O/H) = α × PYQZ_{12+log(O/H) + β}. The dotted red line represents the one-to-one relation, while the dashed black and pink lines are the SF+Comp (all spaxels) and SF linear fits, respectively. Middle panels: disk (green) and tail (blue) spaxels are linearly modeled separately. The error bars are the metallicity uncertainties described in Sect. 4. Bottom panels: residuals from the overall fit (black line in top panel), with standard deviation (std) values shown.
