Examples of CCFs. Left panel: calculated CCF of the IRD spectrum of TOI-1442 (blue) taken on UT 2021 June 25 at the orbital phase 0.33, to the template spectrum of TOI-1634, exhibiting a single peak with width of ~10 km s−1. The autocorrelation function of the TOI-1634 spectrum is overplotted as a reference. Right panel: analogous plot with the CCF of the IRD spectrum of TOI-2445 (blue) taken on UT 2021 October 27 at the orbital phase 0.75.
