TESS FFI cutout (15 × 15 pixels) in the region of NGTS-13 (TIC 454069765; T = 12.11) from which the TESS lightcurve was generated. The red boxes indicate the target pixel aperture mask used to extract the photometry, and the white boxes without a border are the pixels used to determine the sky background. The red star indicates the position of NGTS-13. The yellow crosses indicate TIC 454069767 (ΔT = 1.68, 22.5″ west) and TIC 454069772 (ΔT = 0.6, 57″ southeast). Blue plus signs denote the positions of stars in Gaia DR2 within 1′ of NGTS-13.
