Maps of the out-of-transit residual CCF_loc, and of the in-transit residuals between CCF_intr and their best-fit model (from the joint fit to both transit datasets), during the HD 3167c visit. Transit contacts are shown as green dashed lines. In the top panel, only the continuum of the CCF_intr model was subtracted to highlight the occulted stellar lines. In the bottom panel, the full line model was subtracted.
