I noticed something like a bug with Louis' code. I generated a zero kappa field, that I used to lens maps. Here is the result for a simulation of the CIB (power spectrum by Alex):

There may be an issue on lowscales, where the power spectrum is reduced by a factor 2. The total loss of power spectrum is 2%.

Here is the relative difference of power spectrum:
