Emission lines used in this work and extinction coefficients from the THEMIS dust model (Jones et al. 2017).
| Line | λ (Å) | k(λ) |
|---|---|---|
| [OII] | 3727,3729 | 5.252 |
| Hβ | 4861 | 3.886 |
| [OIII] | 4959 | 3.797 |
| [OIII] | 5007 | 3.755 |
| [NII]1 | 6548 | 2.728 |
| Hα | 6563 | 2.720 |
| [NII] | 6584 | 2.710 |
| [SII] | 6717 | 2.644 |
| [SII] | 6731 | 2.637 |
Notes. [NII]λ6548 is not actually fitted but its flux is setto 1/3 of the [NII]λ6584 flux (theoretically expected ratio; e.g. Alam et al. 2015).
