Image Details
Caption: Figure 3.
Top: residual CCFs obtained by subtracting each observation’s CCF from the out-of-transit template. The in-transit CCFs are colored according to the time from midtransit. For reference, the residual CCFs for the out-of-transit observations are shown in gray, showing no significant deviations above the noise level. Bottom: this panel shows the residual CCFs with time flowing upward on the vertical axis. Horizontal dashed lines show the planet ingress and egress times (first and fourth contacts).
