Image fits in TESS sectors 14 and 40 place two light losses closest to TIC 219752664 and TIC 356014480

We test the positions of two periodic losses of light in selected TESS fields. The Lastovka et al. ULTRASAT-field catalog lists three planet candidates and two nearby false-positive entries in these fields. Their periods are nearly equal within each field. We combine 25 event images from TESS sectors 14 and 40 and fit both a Gaussian and the calibrated TESS pixel response function. Under the supplied cutout sky maps, the 4.11292-day loss is closest to TIC 219752664. The 4.76567-day loss is closest to TIC 356014480. Default Gaussian offsets are 1.34 and 1.67 arcseconds for the first star, and 1.36 and 1.30 arcseconds for the second. Default calibrated-model offsets are 1.77 and 1.19 arcseconds, and 2.03 and 1.05 arcseconds. All 216 tests of time windows and fit regions retain the same closest selected stars. The 50 fits that omit one event and four coordinate tests also retain these choices. The results favor a shared source for the close candidate entries TIC 356014478 and TIC 356014480. A timing match to a nearby rejected entry does not by itself locate contamination. The six-arcsecond candidate pair remains below one TESS pixel. Sky-map errors, unresolved stars, and weaker additional signals remain possible. These measurements do not confirm planets or assign a unique physical host. The package preserves raw cutouts, catalog inputs, calibration files, code, provenance, numerical results, figures, and offline reproduction instructions.
