Top: residual CCF profiles; colours chosen for viewing ease. Bottom: residual map of (a subset of) the time series CCFs, colour-coded by residual flux. Dotted lines at 0 phase and 0 km s^-1 are shown to guide the eye. The travelling “bump” in the CCF_in profiles is evident as a bright streak, as the planet traverses the stellar disc. The transit centre occurs at ~0 km s^-1 in both plots because the orbital motion and systemic RVs were removed.
