Mass-metallicity diagram for the galaxies in our sample with [O iii]λ4363 Å detection (red triangles), compared to the [O iii]λ4363 galaxies with T_e oxygen abundances compiled by Ly et al. (2014, 2015) (open circles and open squares, respectively). The AM13 MZR and ± 1σ uncertainty are shown with green lines. The red line indicates the best-fit MZR from Ly et al. (2016b) for galaxies with [O iii]λ4363 detections.
