Multi-Detector Multi-Component spectral matching and applications for CMB data analysis
J. Delabrouille1, J-F. Cardoso, G. Patanchon1

We present a new method for analyzing multi--detector maps containing contributions from several components. Our method, based on matching the data to a model in the spectral domain, permits to estimate jointly the spatial power spectra of the components and of the noise, as well as the mixing coefficients. It is of particular relevance for the analysis of millimeter--wave maps containing a contribution from CMB anisotropies.
