Comparison of O/H abundance profiles derived from the different O/H maps: X-ray/EUV and pAGB models, and HII and LINER calibration for RXJ0821. The median O/H profile is indicated by the pink line. O/H abundances profile derived from composite and LIN(E)R spaxels using X-ray and pAGB models, and LINER calibration are shown as blue, black, and purple points, respectively, while values obtained from H II spaxels are shown as gray points.
