Temperature estimates and collisionally excited line fluxes used for measuring ionic abundances.
| Ion | Adopted Te | Emission lines for |
|---|---|---|
| ionic abundances | ||
| N+ | Te[N II] | [N II]λ6584 |
| S+ | Te[N II] | [S II]λλ6717, 31 |
| O+ | Te[N II] | [O II]λλ7320, 30 |
| S2+ | Te[S III] | [S III]λ9069 |
| O2+ | Te[S III] + Eq. (B.1) | [O III]λλ4959, 5007 |
Notes. Te[N II] and Te[S III] were directly measured from temperature-sensitive line ratios, while Te[O III] was obtained using Eq. (B.1).
