Scientific paper

We present a new estimator defined in real space to extract the weak lensing convergence from temperature maps of the Cosmic microwave background radiation. This estimator is build upon the minimum variance estimator defined in harmonic space. Despite being by construction suboptimal, its implementation proves less sensitive to the experimental noise and to the bias of the mode coupling derived from the finite size of the map.
