Cross-correlation signatures of Cr I. Left column–Phase stack of the cross-correlation between the transmission spectra and the Cr I mask. The nights N1, N2, N3, and N4 are shown from top to bottom, respectively. In each plot, the orange dashed lines mark the orbital phases corresponding to the second and third contacts. Similarly, the red dashed lines mark the first and fourth contacts. The white solid line traces the expected planetary signal. Right column–K_p−υ_sys planes corresponding to the CCFs shown in the left column. In each plot, the dashed cross marks the expected K_p and υ_sys of the system.
