Impact of residual errors in the atmospheric point spread function on cosmic shear measurements

Zoryanna Alvarez

Abstract: I have been studying chromatic effects on the atmospheric point spread function (PSF) — in particular, measuring how PSF size is correlated with the color of an object.  So far, I have looked at how PSF size (seeing) in r-band is correlated with g-i color, for blackbody spectra of different temperatures and for stellar spectra.

This poster will be displayed on Monday and Tuesday.
