PSF Stability

PSF Stability
PSF Stability This graph shows the effect of FINDS on the variability of the point spread function (PSF. The orange dots show PSF measurements taken at the Keck Observatory on the night of September 29, 2010, when FINDS was used. The black dots show measurements taken without FINDS over a period of 6 years. As the graph shows, FINDS dramatically improves PSF stability. Yale University
