Caption: Figure 3.

The high-resolution imaging contrast curves for TOI-2494 (top) and TOI-5143 (bottom). Each instrument is plotted in a different color, and the gray shaded region illustrates approximately where Gaia Data Release 3 (DR3) would be sensitive to most companions. For TOI-5143, all observations detect a nearby companion, which is shown as a red star.
