SOAR speckle imaging (5σ upper limits) of TOI-1107 (TIC 394561119; top left), TOI-629 (TIC 293853437; top right), and TOI-1982 (TIC 437329044; bottom left) that rules out stellar companions within 3″. The image inset represents the speckle auto-correlation function. Adaptive optics image and contrast curve for TOI-2543 (TIC 270604417; bottom right) taken with the ShARCS camera on the Shane 3-m telescope at Lick Observatory. The contrast curve was generated by calculating the median values (solid lines) and root-mean-square errors (blue, shaded regions) in annuli centered on the target, where the bin width of each annulus is equal to the full width at half maximum of the point spread function.
