K_p – Δv_sys maps of VO, for T1, T2, and T3, using both the VOMYT (McKemmish et al. 2016) and HyVO (Bowesman et al. 2024) line lists. The VO cross-sections were calculated at T = 2800 K and P = 0.1 mbar. The transmission spectra were computed using an isothermal T-P profile and convolved with a 1D Gaussian kernel. The dotted red lines show the expected planetary velocity values, whereas the dashed white lines show the maximum K_p and Δv_sys values.
