Parameters for TH line selection.
| Name | Description | Threshold investigated |
|---|---|---|
| Stime | Slope of the RV drift as a function of time divided by the fitted Gaussian width | [3,4,5] σ |
| of the distribution for all TH lines | ||
| Acorr | Pearson correlation coefficient between the RV drift and its fitted amplitude | [0.3,0.5,0.7] |
| FRcorr | Pearson correlation coefficient between the RV drift and the TH spectrum flux ratio15 | [0.3,0.5,0.7] |
| Zscore | Ratio between the RV drift MAD and median photon-noise error | [3,4,5,] σ |
| Ointervention | Maximum offset in RV drift among all major instrument intervention divided by | [2, 3, 4] σ |
| the median photon-noise error (see Appendix A) |
Notes. Observables for TH line selection optimisation and investigated threshold to reject lines with significant variability. Values in bold font correspond to the threshold used for our optimal line selection, listed in Table D.1.
