摘要：

This paper offers a new point of view on component separation, based on a model of additive components much more flexible than what is used in more traditional approaches. This flexibility is needed to accommodate the complex full-sky observations expected from the Planck space mission, for which it was developed, but it may also be useful in any context where accurate component separation is needed.
