Cross-correlation function for N1 (first row), N3 (second row), and N4 (third row) extracted from the DRS using a G2 mask. Left: cross-correlation function linear profiles as a function of time. The black line indicates the average CCF. Right: two-dimensional maps of the CCFs as a function of orbital phase and RV in the stellar rest frame. The four horizontal black lines show the times of transit contacts. The straight white line shows the expected planetary Keplerian velocity K_p using a planetary mass value of ~0.34 M_J (Zhou et al. 2017).
