Fig. 5
5σ speckle imaging contrast curves of Gemini South Zorro in both filters as a function of the angular separation out to 1.2 arcsec, the end of speckle coherence. The inset shows the reconstructed 832 nm image with a 1 arcsec scale bar. The star, TOI-663, was found to have no close companions to within the angular and contrast levels achieved.
