Median contrast in the dark hole region (−20 λ/D to 20 λ/D in x by −20 λ/D to 20 λ/D in y) as a function of time. Each frame has an exposure time of 1 second. The contrast is shown for three different spectral separations, which are shown in different colors. The three figures are for a 0th (left), 5th (middle), and 7.5th (right) magnitude star as observed by MagAO-X. The final median contrast is almost independent of the spectral separation between the two channels. The smallest spectral separation does lead to the deepest contrasts. The simulations with a fainter star (right) have been done with a lower feedback gain, which increased the convergence time to 25 s.
