Contrast (upper panel) and FWHM (lower panel) of the local CCF_loc from the planet-occulted regions as a function of orbital phase. A significant decrease in contrast occurs along the transit chord, while the FHWM remains stable overall. The solid horizontal lines correspond to the contrast and FWHM of the disk-integrated CCF_DI measured outside of the planet transit. Vertical dotted lines indicate the planet contacts. The gray line in the upper panel shows our best fit for the local contrast, assuming it varies linearly from the pole to the equator of the star.
