Noise estimation in CMB time-streams and fast map-making. Application to the BOOMERanG98 data

Abstract

We describe here an iterative method for jointly estimating the noise power spectrum from a CMB experiment's time-ordered data, together with the maximum-likelihood map. We test the robustness of this method on simulated Boomerang datasets with realistic noise.
