Telescope Optics and Weak Lensing: PSF Patterns due to Low Order Aberrations
Mike Jarvis, Paul Schechter, Bhuvnesh Jain
In weak lensing investigations, galaxy shapes are deconvolved for the effects of the point spread function (PSF) using stellar images. In this paper we use physical models of the t…

On Combining Lensing Shear Information from Multiple Filters
Mike Jarvis, Bhuvnesh Jain
We consider the possible gain in the measurement of lensing shear from imaging data in multiple filters. Galaxy shapes may differ significantly across filters, so that the same gal…

Principal Component Analysis of PSF Variation in Weak Lensing Surveys
Mike Jarvis, Bhuvnesh Jain
We introduce a new algorithm for interpolating measurements of the point-spread function (PSF) using stars from many exposures. The principal components of the variation in the PSF…
