Contrast curves for TOI-2257 b from high angular resolution imaging. The top plot shows the results of the Alopeke speckle instrument on Gemini North. The bottom plot shows the speckle interferometry taken by SPP at the Sternberg Astronomical Institute. Both plots have the final reconstructed image inlaid in the upper right. Neither instrument detects a nearby companion with a magnitude within 4.5 mags of the target star.
