Caption: Figure 6.

Difference images for TOI 4342 b and TOI 4342 c, made using 20 × 20 pixel cutouts of the Sector 27 TESS FFIs (top). A close-up of the central 5 × 5 pixels is also shown (bottom). The third column shows the average of out-of-transit images, which should represent a direct image of the field near the target star. The target TIC 354944123 is indicated with a pink star, while nearby stars down to ΔT = 4 mag are plotted as white circles with sizes scaled by brightness. The difference images for both planet candidates indicate the transit sources are collocated with the target star. The color bars are all in units of electrons per second.
