TESS target pixel file image of TOI-2431 in Sector 31. The electron fluxes are shown with the color bar. The red-bordered pixels highlight the pixels used for the PDCSAP light curve. The TESS pixel scale is approximately 21″. The size of the red circles indicates the TESS magnitudes of all nearby stars and TOI-2431 (white cross). Gray arrows show the proper motion directions of the stars in the field.
