Abstract: Although the ``internal linear- combination method ILC is a techniquewidely used for the separation of the Cosmic Microwave Background signal fromthe Galactic foregrounds, its characteristics are not yet well defined. Thiscan lead to misleading conclusions about the actual potentialities and limitsof such approach in real applications. Here we discuss briefly some facts aboutILC that to our knowledge are not fully worked out in literature and yet havedeep effects in the interpretation of the results.
