85 T16 candidate pairs more than two arcminutes apart pass a timing test on the same detector with nominal sector windows
We test the revision 3 T16 candidate table for shared timing on each TESS sector, camera, and CCD. A pair must have periods within one percent and a phase-drift score at most 0.2 in units of the smaller catalogue duration. Nominal sector windows define the test. Of 10,925 rows with coordinates, 675 pairs pass. Of these, 85 pairs are more than two arcminutes apart and involve 53 stars. Uniform-phase controls give a mean of 12.55 distant pairs and a maximum of 28 in 10,000 trials. These controls do not model all instrument and selection effects. A 12-star group contains 48 distant pairs. Six inspected T16 light curves show dips with one common ephemeris. Two stars 6.80 degrees apart have positive local depths in five predicted event windows. A separate sector 5 pair does not show the same shared dip in QLP. Adding one day to each end of each nominal window leaves 82 distant pairs. The contribution provides timing flags and checks, not physical source assignments or planet confirmations. The package includes source data, provenance, code, results, and figures.

We use its cycle-invariant finite-window phase rule and conditional uniform-phase control design. We apply the method to T16 with nominal sector windows, global same-detector separations, and separate light-curve checks.
