The Great-3 challenge is now complete and the winners decided. We have also now deactivated the post-challenge leaderboards, so no more submissions can be made at all.

CMU experimenters This is a team for Rachel Mandelbaum's group at CMU to experiment with some crazy ideas that probably won't work, but are kind of fun to think about. * 4
COGS Capitalizing On Gravitational Shear Team based primarily at University of Manchester and University College London, and lead by Sarah Bridle. Most entries will use the im3shape code described in http://arxiv.org/abs/1302.0183. * 38
DeepZot Team members: Daniel Margala and David Kirkby at UC Irvine 0 0
E-HOLICs E-HOLICs method is developed for aim of precise and fast shear analysis. E-HOLICs method is moment method like KSB method , but use elliptical weight function for avoiding one of systematic errors. 3000 58
