Abstract :
The authors address the challenge of extracting high-precision measurements of cosmological parameters from upcoming megapixel cosmic-microwave data sets. They discuss the computational challenges associated with current methods for going from the time streams to multifrequency sky maps, from these maps to the different sky signals, and from there to the statistical properties of the cosmic microwave background
