Local contrast of the stellar lines occulted by HD 3167b (green) and HD 3167c (orange), derived from the fits to individual exposures (Sect. 4.3, Figs. 5 and 7). Solid black lines show the best-fit model for the contrast variations as a function of the squared latitude coordinate (ranging from 0 at the stellar equator to 1 at the poles), after convolution by the HARPS-N and ESPRESSO LSFs. We note that the models were derived from the RMR fit to the combined datasets.
