A number of tools have been made within the DES Weak Lensing Working Group for analyzing, processing, and testing our data.

Galaxy Shape Measurement

Two galaxy shape measurement codes were used to make catalogs from SV data:

• ngmix by Erin Sheldon

• im3shape by the Im3shape Team

Shear Catalog Testing

A suite of tests are run on DES shape catalogs to ensure their accuracy. They are collected here:

• DESWL repository

2-pt Function Estimation

A number of different 2-pt statistical methods were used on DES shape catalogs:

• TreeCorr by Mike Jarvis

Cosmological Parameter Estimation

After 2pt function measurements have been made cosmological models can be tested against the data using MCMC or related methods. We use these codes in DESWL:

• CosmoLike

• CosmoSIS (DES-SV instructions)
