Cross-correlation map of TiO in K_p − V_sys space. Top panel: projected orbital velocity (horizontal dashed line) and systemic velocity (vertical dashed line) where the planetary signal is expected. Bottom panel: one-dimensional cross-correlation function at the expected orbital velocity. The noise-level is at 10⁻⁶. The horizontal thermometer lines at the bottom of the panel show the expected absorption depth is predicted by isothermal models for varying temperatures assuming a perfect line list. The temperature step is 200 K. The thermometer lines at the top of the panel are corrected by a factor of 6, empirically suggested by Prinoth et al. (2022) and Prinoth et al. (2023) to match the observed TiO absorption with the prediction.
