We repeat the analysis from yesterday, only at the beginning we replace all kappa pixels above 0.1 (resp 0.3) with 0.1 (resp 0.3) and see how the effect of lensing on variance/skewness/curtosis change. For Planck flux threshold, full magnification.

We clearly see that restricting maximal values of kappa in the positive kappa tail decrease the effects of lensing significantly.
