Full-sky CMB lensing reconstruction in presence of sky-cuts

Understand

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.
