heal.abstract	We point out that, in the calculation of 2ΔTc from Eliashberg theory of superconductivity, all the boson spectra can be mapped systematically on the subset of two Einstein peaks spectra which, with proper choice of the parameters, give within of a few percent the same result as the original spectra. This allows to extract from 2ΔTc the maximum information on	en
