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

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/2318We 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.7 pages, 6 figures, to appear in proc. of the MPA/ESO/MPA conference "Mining the Sky", Garching, July 31 - August 4 2000AstrophysicsNoise estimation in CMB time-streams and fast map-making.
