Target pixel files of TOI-3493 in TESS sectors 37 (left) and 64 (right). The electron counts are color-coded. The red-bordered pixels are used in the simple aperture photometry. TOI-3493 is represented with a circle marked with #1. The other stars are represented with red circles and the size of the circle related to the magnitude difference. The other stars in the field are relatively faint, and hence appear as tiny dots.
