TL;DR: In this paper, the authors proposed an acquisition strategy and reduction pipeline for speckle attenuation and high contrast imaging is demonstrated to significantly get better detection limits with longer integration times at all angular separations.

TL;DR: In this paper, an algorithm to construct an optimized reference PSF image from a set of reference images is presented. But this image is built as a linear combination of the reference images available and the coefficients of the combination are optimized inside multiple subsections of the image independently to minimize the residual noise within each subsection.

TL;DR: Speckles dominate shot noise within the halo of adaptively corrected bright star images and, consequently, impose severe limits on ground-based attempts to directly detect planets around nearby stars as discussed by the authors.

TL;DR: The results of the Gemini Deep Planet Survey as mentioned in this paper were obtained with the Altair adaptive optics system at the Gemini North telescope, and angular differential imaging was used to suppress the speckle noise of the central star.
