Caption: Figure 2.

A 5′ field of view from PEST centered on the target (center object, ID #6). An example TESS aperture is overlaid in the same scale (cyan). Identifier numbers come from a brightness-ordered list of Gaia stars (red × points) in the area. Given TESS's pixel size and PSF width, it is typical to check for NEBs within 2.′5 of the target (orange circle). NEB check results for detectable neighboring stars are displayed in Table 1.
