Rectangular dark hole for the MagAO-X PAPLC. The inner-working angle is 1.5 λ/D and the outer-working angle is 23 λ/D. The dark hole is 46 λ/D wide. The white border indicates the area that is nulled by iEFC. The left figure shows the speckles with AO residuals before control and the middle figure after iEFC control. The right figure shows the same dark hole after iEFC but without AO residuals.
