Pixel-by-pixel analysis of the quadruple candidate TIC 302537339 for Sector 32. First row, left panel: 9 × 9 TESS pixels difference image centered on the target. There are several nearby field stars bright enough to contaminate the target’s lightcurve and mimic a quadruple candidate. First row, right two panels: lightcurve (left) from the two pixels centered on the target (right, white contours). Second and third rows: same as above but for the nearby field stars. None of these show features resembling the eclipses seen in the target’s lightcurve, confirming the signals originate from the vicinity of TIC 302537339. For clarity, the individual panels are outlined with black contours.
