A simple fitting method (gfit) for galaxy shape measurement in weak lensing surveys
Marc Gentile, Frederic Courbin, Georges Meylan
It is anticipated that the large sky areas covered by planned wide-field weak lensing surveys will reduce statistical errors to such an extent that systematic errors will instead b…
Interpolating point spread function anisotropy
M. Gentile, F. Courbin, G. Meylan
Planned wide-field weak lensing surveys are expected to reduce the statistical errors on the shear field to unprecedented levels. In contrast, systematic errors like those induced…
Image Analysis for Cosmology: Results from the GREAT10 Star Challenge
T. D. Kitching, B. Rowe, M. Gill +13
We present the results from the first public blind PSF reconstruction challenge, the GRavitational lEnsing Accuracy Testing 2010 (GREAT10) Star Challenge. Reconstruction of a spati…
Image Analysis for Cosmology: Results from the GREAT10 Galaxy Challenge
T. D. Kitching, S. T. Balan, S. Bridle +25
In this paper we present results from the weak lensing shape measurement GRavitational lEnsing Accuracy Testing 2010 (GREAT10) Galaxy Challenge. This marks an order of magnitude st…
