Raw contrast curves as a mean radial profile, for on-sky observations of HD 142527 and measured with the instrument’s internal source, for the narrowband 875 filter on the left and the broadband z’ filter on the right. In both panels, the darker solid line (sky) shows the on-sky contrast, the lighter solid line (lab) shows the measured contrast with the internal source, the dashed black curve (sky reference) shows the on-sky non-coronagraphic PSF, and the dashed grey line (lab reference) shows the measured non-coronagraphic PSF with the internal source. In this experimental setup, all elements are in the beam (bump mask, forward PIAA lenses set, focal plane mask, Lyot stop, inverse PIAA lenses set), and the focal plane mask is taken out of the beam only to measure the reference. In the left panel, the peak at ∼9 λ/D in the on-sky curves is due to artificial DM speckles that were mistakenly not turned off.
