Pixel model fits in four TESS sectors leave the host of the TOI-6047.01 dip uncertain

We tested which star supplies the broad TOI-6047.01 dip in public TESS data. We fitted pixel response functions to event loss images in Sectors 59, 71, 72, and 73. The test retains 36 events. The four best positions are 0.92 to 4.55 arcseconds from the catalog star. These are point estimates, not upper limits. We preserve 1,000 whole-event position resamples per sector. Gaia DR3 lists neighbors at 2.64 and 6.36 arcseconds. Under an illustrative position error model, the FITS sky coordinates favor the nearest neighbor. A shift based on the static central image favors the catalog star. That shift is not a calibrated correction. The reversal shows that the small event intervals alone do not give a reliable host. This work extends an earlier central-pixel test to four quantitative sector fits. It supplies a compact pixel dataset, measured positions, model checks, source records, and code. It does not establish a planet, a binary, or a cause for the broad duration.
