covariance_testing

Instructions:

Please generate a 3x2pt Non-Gaussian covariance matrix for the parameters below. Except for area this corresponds to a DES Y1 covariance matrix assuming a circular survey geometry scaled to 5000 deg^2. Note that in the covariance released as part of the DES Y1 release the actual DES footprint is assumed in order to compute the correct noise terms. Here we neglect the specific DES footprint.

Goal:

Code comparison at the precision required for an approximate DES Y3 analysis
