Clustering and weak lensing from DES Y1¶
DES likelihood, independent Python implementation. Well tested and agrees with likelihoods in DES chains for fixed nu mass.

If you use any of these likelihoods, please cite them as:

Likelihoods of the DES Y1 data release, described in the paper mentioned above:
des_y1.joint(a shortcut for the combination of the previous three)
To use any of the DES likelihoods, you simply need to mention them in the
likelihood block, or add them using the input generator.
The corresponding nuisance parameters will be added automatically,
so you don’t have to care about listing them in the
The nuisance parameters and their default priors can be obtained as explained in Getting help and bibliography for a component.
This likelihood can be installed automatically as explained in Installing cosmological codes and data.
