Comparison between measurements of EW(Hα) values (left-hand plot) and [OIII]Hβ ratios (right-hand plot) from this work (y-axis; using a 3″ aperture) and Sánchez et al. (2018, x-axis) in a logarithmic scale. The measurements (in blue circles) shown here correspond to the AGN-candidate subsample from Sánchez et al. (2018) The solid black line in both plots shows the one-to-one ratio that the values should follow if they have the same value. The gray dashed line in the plots shows a 1D polynomial fit to the distribution.
