Overview of some validation tests of TOI-1807 b. Panel a shows the flux normalized short-cadence light curve of TOI-1807; red triangles indicate the central time of the TOI-1807 b’s transits. Panel b illustrates the in- or out-of-transit centroid test, for sectors 22 and 23; within the errors, the transits are associated with the central star. Panel c is the flattened light curve, folded with the period of TOI-1807 b (-0.549 day).
