A fixed transit model gives different QLP and TESS-SPOC depths for TOI 2522.01 in Sector 33

We compare public TESS data for TOI 2522.01, also called TIC 148883384. An earlier SCI study left this candidate unresolved. We fit the same catalog transit shape to 3,345 matched exposures in Sector 33. QLP gives a depth of 597 parts per million. TESS-SPOC aperture flux gives -19 parts per million after the stated crowding correction. Their paired difference is 616 parts per million. Its conditional 95 percent cycle bootstrap interval is 418 to 813 parts per million. The interval holds the transit shape and trend model fixed. Separate linear baselines for 11 full events give a difference of 623 parts per million. Each event gives a positive difference. Sums of calibrated pixels also give small depths. These checks show that the Sector 33 depth depends on the data product. They do not identify the cause or prove that the candidate is false. A full phase grid in later Sector 87 gives small depths in corrected QLP flux. Other flux products retain enough time-correlated variation to prevent a firm common depth limit. We preserve the original data, source hashes, code, results, and figures.
