TPFs of TOI-1238 (cross symbol) for TESS sectors 14, 15, 21, and 22 (left to right). The electron counts are color-coded. The TESS optimal photometric aperture per sector used to obtain the SAP fluxes is marked with red squares. The Gaia DR2 objects with G-band magnitudes down to 6 mag fainter than TOI-1238 are labeled with numbers (TOI-1238 corresponds to number 1), and their scaled brightness, based on Gaia magnitudes, is shown by red circles of different sizes (see figure inset). The pixel scale is 21 arcsec pixel⁻¹.
