Spatial and spectral resolution of SISTINE-3 calculated using the Si III line at 1206.5 Å. Left: Si III lines of α Cen A and B. The larger emission line is from A and the smaller is from B. The lines are separated by ∼7″, which matches the predicted on-sky separation of the stars. Right: Si III emission of α Cen A.
