RMR fits of HD 209458b (shown for epoch 1) and WASP-76b (shown for epoch 2). Maps are plotted as a function of rv in the star rest frame (in abscissa) and orbital phase (in ordinate). Green dotted lines show transit contacts. The masked streak in WASP-76 maps is contaminated by the planetary atmosphere. Top panels: CCFs of intrinsic spectra, colored with flux. Green solid lines shows the best stellar surface rv models. Bottom panels: residuals over the full epochs. Out-of-transit values show the CCFs of differential spectra, and in-transit values the difference between the CCFs of intrinsic spectra and their best-fit models (scaled to the out-of-transit level). The slanted in-transit features aligned with the surface rv model of HD 209458 may arise from stellar lines close to the CCF mask lines.
