Average in-transit excess absorption in the planetary frame for all three visits. The error bars are underestimated because they only include the photon noise, read noise, and flat-fielding error, not systematics. Visits b and c2 are directly comparable because they both include a full transit and baseline on both sides, but c1 is not directly comparable because it is a partial transit. The data behind this figure are available in machine-readable format.
