Comparison of the radial distributions of oxygen abundances in the galaxy determined from the independent MaNGA observations of the same galaxy. In each panel, the symbols denote the median values of the O/H in bins of 0.05 in the fractional radius, R/R₂₅, and the bars show the scatter in O/H about the median value in the bins. The lines show the relations we determined for the radial abundance distributions. The horizontal bar indicates the point spread function in the MaNGA measurements.
