Comparison of fluxes in forbidden optical emission lines obtained with the NBURSTS technique for X-ray-selected DR19 galaxies (x-axis, this paper) with previously published results (y-axis). The left panel compares 101 galaxies in common with the RCSED catalog (Chilingarian et al. 2017). The right panel compares 75 galaxies in common with the RCSED SDSS DR17 data release (Blanton et al. 2017). The dashed black line represents the 1:1 relation. The fluxes we obtained agree well with SDSS-IV DR17 data and are correlated with RCSED.
