Tests of 37 TESS sectors do not detect a 1,010.56-day transit time wave in TOI-700 d or e

TOI-700 d and e have orbital periods near a 4:3 ratio. We test a transit-time wave at the fixed period of 1,010.560485 days. We use public two-minute TESS flux data from 37 sectors. Coverage rules retain 22 transits of d and 27 transits of e. Each planet has its own free linear clock and common transit depth. The wave improves chi-square by 2.31 for d and 2.36 for e. In 400 residual-rotation trials per planet, the chance probabilities are 0.621 and 0.643. The data do not establish a wave or an opposite phase between the planets. An approximate 95% profile region extends to grid upper edges of 26 minutes for d and 47 minutes for e. These values depend on the fixed transit shape and local stationary-noise model. At a 30-minute injected wave, the region includes the true coefficients in 92.4% of trials for d and 97.9% for e. They are not mass or eccentricity limits. Flux controls, shape changes, season tests, and signal trials show the scope of the result. We provide verified source records, local flux data, source code, figures, and per-event flux-likelihood tables.

    The near-resonant timing theory gives the fixed period used for this targeted test. The test does not establish resonance or infer masses.
