Fit to WASP-76 disk-integrated CCFs, computed with the ESPRESSO DRS F9 mask. Top panel: the dashed black profile is the Gaussian best-fit to the CCF in the last exposure (blue profile, phase −0.0162) before the stellar line is too contamined by the planetary signal (red area) to be accurately fitted. Blue areas are never contaminated by the planet, and used to measured the continuum. Bottom panel: rv residuals from the Keplerian model. Orange squares and green disks were derived from CCFs with no strong planetary contamination in epochs 1 and 2. Matching black symbols (shown without errors for clarity) were derived without excluding planetary ranges from the fits.
