Making cosmic microwave background temperature and polarization maps with MADAM

摘要

MADAM is a CMB map-making code, designed to maketemperature and polarization maps of time-ordered data of totalpowerexperiments like P LANCK. The algorithm is based on the destripingtechnique, but it also makes use of known noise properties in theform of a noise prior. The method in its early form was presented inan earlier work by Keih?nen etal.(2005, MNRAS, 360, 390).In this paper we present an update of the method, extended tonon-averaged data, and include polarization. In this method thebaseline length is a freely adjustable parameter, and destriping canbe performed at a different map resolution than that of the finalmaps. We show results obtained with simulated data. This study isrelated to P LANCK LFIactivities.Key words: cosmology: cosmic microwave background - methods: data analysis
