Modeling correlations in the atmospheric point spread function

Peter Kiernan

We study the impact of residual (uncorrected) errors in the modeling of the atmospheric point spread function (PSF) on measurements of cosmic shear, with a particular focus on uncorrected correlated errors in shape and size of the PSF. We take advantage of cosmological parameter estimation and likelihood packages developed within DESC to estimate the impacts of these uncorrected errors.


This poster will be displayed on Monday and Tuesday.
