List of atomic transitions taken into account in the simulations.
| Species | Transition | Wavelength (nm) | References | Width (nm) | Comments |
|---|---|---|---|---|---|
| O I | 1S → 1D | 557.7 | (Kramida et al., 2022) | 0.2 | Forbidden transition; lifetime ∼ 1 s. |
| O I | 1D → 3P | 630 and 636 and 639 | (Kramida et al., 2022) | 0.2 | Forbidden triplet transition; lifetime ∼110 s. |
| O I | 3p5P → 3s5 S0 | 777.2 and 777.4 and 777.5 | (Kramida et al., 2022) | 0.2 | Triplet transitions. |
| O I | 3p3 P → 3s3 S0 | 844.6 | (Kramida et al., 2022) | 0.2 | Triplet transitions but with very close lines. We consider this line as a single line. |
| O II | 2P → 2D | 732.0 | (Kramida et al., 2022) | 0.2 | |
| N I | 2D → 4S | 520 | (Kramida et al., 2022) | 0.2 | Forbidden transition; lifetime ∼9.95 h. |
| N II | 3d3 F → 3p3 D | 500.1 and 500.5 | (Kramida et al., 2022) | 0.2 | |
| N II | 3p3 D→3s3 P | 568.0 | (Kramida et al., 2022) | 0.2 | In fact four different lines. Only the 568.0 nm has a significant cross-section. The other three have been included in the other lines (see below). |
| N I and N II | 81 lines listed in Table 18 of Mangina et al. (2011) | From 380 to 900 | (Mangina et al., 2011) | 0.2 | The weak lines of the two previous multiplets have been included in these 81 lines. |
