Allow for cross-z covariance in P1D data #65

Open andreufont opened 2 years ago

andreufont commented 2 years ago

The P1D estimator used by Naim (optimal quadratic estimator) models the covariance between redshift bins, but the current setup assumes that the likelihoods of each redshift bins are independents.

I will investigate whether this could be easily modified to allow for covariances of size (Nz Nk) x (Nz Nk).
