Cosmology from Cosmic Shear with DES Science Verification Data
The DES Collaboration

Likelihood Code.

Some of these figures were made using cosmic shear likelihood code which is implemented in both the CosmoSIS and CosmoLike parameter estimation codes. Instructions for using it via the former are available here.
