CCFs of the stellar surface occulted by the planet, CCFres, for our three nights of observations (with the date indicated as column title from left to right). Top: residual CCFs are shown in black for the out-of-transit data and randomly colored for the in-transit data. The vertical dashed lines show the normalization regions (indicated by the two outer lines and defined by v ≤ 31.76 km s-1 or v ≥ 52.13 km s-1), the FWHM of the master CCF profile (middle two lines at v = γ ± 3.37 km s-1), and the systemic velocity γ (central line at v = 41.73 km s-1). Bottom: residual map of the time series CCFres in phase and color-coded by residual flux. The horizontal dashed lines represent the four contact points of the transit. As for the radial velocity series (Fig. 2), no obvious traveling planet signature is noticeable (see Fig. 4).
