Details of the line shifts and FWHMs measured for the main emission lines.
| Ion | Component | Peak velocity [km s−1] | FWHM [km s−1] |
|---|---|---|---|
| Mg I] 4571 | – | −1000 | 2000 |
| [O I] 5577 | – | −1500 | 1800 |
| Na I D | – | −1000 | – |
| [O I] 6300 | Narrow blue | −1700 | 500 |
| Wide blue | −1100 | 2000 | |
| Narrow red | 1300 | 500 | |
| Wide red | 1400 | 2000 | |
| Hα | Wide rest | 0 | 5300 |
| Intermediate blue | −1800 | 1600 | |
| [Ca II] 7300 | – | 0 | 4000 |
| O I 7774 | – | −1500 | – |
Notes. Na I D and O Iλ7774 features are contaminated by nearby emissions, and thus the FWHM is not measured.
