Notes. Line ratios are normalized to the flux of [OIII]0.5007 μm emission line.
Average of O/H values from II Zw 40, Mrk 71, Mrk 930, and Mrk 996. Their metallicity range is 7.85 < 12 + log(O/H) < 8.10.
The template TM_0.02_solar does not include emission lines redder than [SII] 0.6731 μm because only optical spectral lines are available. The HeI1.087 μm flux have been calculated from HeI 0.5876 μm, using the line ratio (HeI 1.087 μm/HeI 0.5876 μm) derived using the templates TM_0.2_solar and TM_0.02_solar.
