[Summary] In this posting, I show some results of the reconstruction of the CMB lensing kappa map from the signal only or signal+noise+foreground simulations. I used two quadratic estimators, TT and EB, and show that the reconstructed kappa map looks agree with the input kappa map even after including the noise and foreground. However, the reconstruction noise becomes larger at smaller scales of the reconstructed kappa. This could affect the delensing efficiency.
