Intrinsic CCF map of WASP-76 in epoch 2, plotted as a function of rv in the star rest frame (in abscissa) and orbital phase (in ordinate). Values are colored as a function of normalized flux, unveiling the track of local stellar lines occulted by the planet along its transit chord (green dotted lines show transit contacts). The magenta line shows the planet orbital track, along which was excluded the range contaminated by its atmosphere. CCFs were computed with ANTARESS mask built from WASP-76 data (Sect. 8.1).
