标题： Multi-Detector Multi-Component spectral matching and applications for CMB data analysis

摘要： 我们提出了一种分析包含多个分量贡献的多探测器地图的新方法。 我们的方法基于在频谱域中将数据与模型匹配，可以同时估计各分量和噪声的空间功率谱以及混合系数。 这种方法对于分析包含宇宙微波背景（CMB）各向异性贡献的毫米波地图尤为重要。 显示英文摘要

摘要： 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.
