TESS target pixel file of Sectors 80 (upper panel) and 81 (lower) centred on Kepler-1601. The red circle labelled 1 is marked by a white cross. The orange squares delimit the pixels used by the SPOC pipeline to perform the aperture photometry of Kepler-1601. KIC 2831097 is the star labelled 4 in both panels. All sources from the Gaia DR3 catalogue down to a magnitude difference of 4 are shown as red circles, and the size is shown in the inserted legend. The colour bar on the right indicates the electron counts for each pixel. Both plots were built using the code tpfplotter (Aller et al. 2020).
