adding function to produce diagonal theory covarinace matrix for nnfit
Created by: tgiani
Here I ve added a function to produce a diagonal theory covariance matrix to be used in a fit.
Note that a similar function was already present in line 628 of theorycovariance.py
. In principle it would be enough to edit that function instead of defining a new one, but I m not sure if that one is already used somewhere else. If not, I can just edit it.
This function has to be used in config.py
within produce_nnfit_theory_covmat
instead of theory_covmat_custom
.
