我们考虑了点源和银河系污染引起的天空切割的情况下，宇宙微波背景辐射透镜势及其功率谱的重建。这两种影响是分开处理的。被点源污染的小区域使用高斯约束实现来填充。在透镜重建之前，银河平面简单地使用切趾掩模进行掩模。该算法恢复了透镜势的功率谱，没有明显的偏差。

We consider the reconstruction of the CMB lensing potential and its power spectrum of the full sphere in presence of sky-cuts due to point sources and Galactic contaminations. Those two effects are treated separately. Small regions contaminated by point sources are filled in using Gaussian constrained realizations. The Galactic plane is simply masked using an apodized mask before lensing reconstruction. This algorithm recovers the power spectrum of the lensing potential with no significant bias.
