Summary of the hydrogen Balmer line detections.
| C | v | FWHM | δ(a) | |
|---|---|---|---|---|
| [%] | [km s−1] | [km s−1] | [%] | |
| Hα | 0.91 ± 0.04 | 2.1 ± 0.8 | 44.3 ± 1.8 | 0.68 ± 0.03 |
| Hβ | 0.68 ± 0.04 | − 1.7 ± 1.3 | 46.3 ± 2.5 | 0.45 ± 0.03 |
| Hγ | 0.44 ± 0.07 | 0.9 ± 2.9 | 43.5 ± 5.5 | 0.31 ± 0.04 |
| Hδ | 0.61 ± 0.13 | − 4.6 ± 2.2 | 25.6 ± 5.7 | 0.42 ± 0.09 |
| Hɛ | 0.39 ± 0.14 | − 15.0 ± 5.0 | 29.5 ± 10.0 | 0.26 ± 0.09(b) |
| Hζ | ≤0.50 | – | – | ≤0.34(b) |
Notes. (a) The absorption depth is averaged over the line full width (see Wyttenbach et al. 2017), takes systematic noise into account, and is used to compute the line detection significance. (b) Hɛ is not statistically detected. For Hζ we show the 3σ upper limit assuming a Gaussian line shape with a fixed v = 0 km s−1 and FWHM = 30 km s−1.
