Poster Title: Disentangling Stellar Population Properties from Spectroscopic Data
Abstract: The derivation of physical properties (age, metallicity, IMF, element abundance ratios) from the integrated light of stellar populations is handicapped by the fact that variations in those properties led typically to degeneracies in the observational space. Trying to solve this problem, many authors are seeking for individual and narrow absorption features which are sensitive to one physical parameter and not to the others. But this typically led to the analysis of individual and narrow spectral features which demand high signal-to-noise ratios. Here we will discuss how the functional dependence of colors and line-strength indices on signal-to-noise ratio allows the definition of a suitability parameter that can help to identify the best spectral features to face the disentangling of the observed degeneracies.
