Final ADI and ASDI reduced images of HD142527. Top row: B_Ha, Cnt_Ha, and N_Ha filter images resulting in the lowest FPFs (1.5 × 10⁻¹¹, 2.2 × 10⁻⁹, and < 10⁻¹⁷, corresponding to S/Ns of 13.1, 9.8, and 26.6, respectively). Bottom row: final images after ASDI reduction for B_Ha-Cnt_Ha and N_Ha-Cnt_Ha frames (4.4 × 10⁻¹⁶ and < 10⁻¹⁷, corresponding to S/Ns of 22.7 and 27.6). We give the number of subtracted PCs and the radius of the central mask in milliarcseconds in the top left corner of each image. The color scales are different for the two rows. Because all images of the top row have the same color stretch, the detection appears weaker in the continuum band.
