Median N/O ratio gradient as a function of the galaxy mass for a sample of galaxies with a flat oxygen abundance gradient. The abundances are either derived from the R calibration (blue solid) or using the HCM method (red dashed). Error bars show the standard deviation divided by the square root of the number of data points in each mass bin. For reference, a horizontal dashed line shows the zero level of the N/O ratio gradient.
