Line profile parameters obtained by fitting a Gaussian function to the average line profile in Fig. 8.
| Lines | vcenter [km s−1 ] | FWHM [km s−1 ] | Line depth | Model line depth | Reff [Rp] | |
|---|---|---|---|---|---|---|
| WASP-33b | Ca II H&K | –1.9 ± 0.7 | 15.2 ± 1.5 | (2.02 ± 0.17)% | 0.235% | 1.56 ± 0.04 |
| Ca II IRT | 2.0 ± 0.7 | 26.0 ± 1.7 | (0.67 ± 0.04)% | 0.064% | 1.22 ± 0.01 | |
| KELT-9b | Ca II H&K | 3.2 ± 0.7 | 27.5 ± 1.8 | (0.78 ± 0.04)% | 0.162% | 1.47 ± 0.02 |
| Ca II IRT | –2.2 ± 2.2 | 24.4 ± 5.1 | (0.29 ± 0.05)% | 0.076% | 1.19 ± 0.03 | |
Notes. Here vcenter is the measured RV shift of the line center compared to the theoretical line center. The model line depth is the average line depth from the Ca II transmission model. Reff is the effective radius at the line center calculated using the observed line depth value and the photometric transit depth.
