Table A.1
Value of the dispersion on a single-resolution element in the wings of the CCF of all considered bands for observations of a single transit.
| Band name | Instrument simulated | Precision (1 transit) | Notes |
|---|---|---|---|
 |
HARPS(-N) | 51 ppm | Allart et al. (2017) reported 34 ppm with three transits, |
| equivalent to 58 ppm with one transit, | |||
| with a mask similar to that adopted in this paper | |||
 |
ESPRESSO | 20 ppm | |
 |
GIANO | – | Accuracy limited by telluric contamination |

| Y band | GIANO | 33 ppm | |
| J band | GIANO | 31 ppm | |
| H band | GIANO | 27 ppm |
Notes. The GIANO resolution element is larger, which is why the precision is higher. However, this results in a more poorly sampled CCF (see Fig. 3).
