Map of the residual CCFs during the 16-02 (top) and the O7-03 (bottom) nights as a function of orbital phase and RV in the stellar rest frame. Colors indicate flux values. The horizontal dashed black lines indicate transit contacts. In-transit residual CCFs show the average stellar line profiles from the regions occulted by KELT-11 b across the stellar disk. The crosses are the measured centroids of the CCFs, which correspond to the local RVs of the planet-occulted regions.
