Angular Differential Imaging (ADI) and Principal Component Analysis (PCA) are the most used approaches to suppress the quasi-static structure presents in the Point Spread Function (PSF) for revealing planets at different separations from the host star. In this work, we present the comparison between ADI and PCA applied to System of coronagraphy with High order Adaptive optics from R to K band (SHARK-NIR), which will be implemented at Large Binocular Telescope (LBT). The comparison has been carried out by using as starting point the simulated wavefront residuals of the LBT Adaptive Optics (AO) system, in different observing conditions. Accurate tests for tuning the post processing parameters to obtain the best performance from each technique were performed in various seeing conditions (0:4"-1") for star magnitude ranging from 8 to 12, with particular care in finding the best compromise between quasi static speckle subtraction and planets detection. | Titolo del convegno: | Adaptive Optics Systems V | Luogo del convegno: | Edinburgh, United Kingdom | Periodo del convegno: | 26 June - 1 July 2016 | URI: | http://hdl.handle.net/20.500.12386/28530 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9909/1/A-comparison-between-different-coronagraphic-data-reduction-techniques/10.1117/12.2232792.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510601970 9781510601987 |
