TESS target pixel file of TOI-4552 from sectors 12 (left), 39 (centre) and 66 (right), created with TESS-cont (Castro-González et al. 2024). The aperture mask is highlighted in red and the pixel size is 21″. TOI-4552 is highlighted in white with the mesh pattern. The heatmap depicts the per-pixel relative flux contributed by TOI-4552, used to optimise the aperture mask. The five stars that contaminate the lightcurve of TOI-4552 the most are highlighted, with the size of the source being a relative measure of the contamination. The TESS SPOC lightcurves are already corrected for the dilution effect from these five sources.
