Upper panel: the oxygen abundance (O/H)SDSS determined from the SDSS spectrum vs. abundance (O/H)PLR given by the purely linear O/H – Rg relation at this radius. The solid line indicates equal values. The dashed lines show the ±0.05 dex deviations from unity. Lower panel: the same as the upper panel but for the (O/H)BLR given by the broken linear O/H – Rg relation.
