I changed the parameters for LensPix in order to see what changed in the power spectrum. Those plots have been obtained with a zero field for kappa. The 'theory - code' on the first plot is a code from Joel/Alex, similar to CAMB.
Loss of energy here means the sum of Cl over all l.
I will check the mocks on this site, and see if we can increase the agreement with theoretical plots.
