In this letter, we investigate the reliability of this method by applying it to some toy models with known spectra. We find that in most instances the technique cannot be trusted to give a reliable result.287 - 293 (7) page(s)application/pdfenIn CopyrightAstronomy & AstrophysicsPhysics, NuclearPhysics, Particles & FieldsPhysicsPHYSICS, MULTIDISCIPLINARYTECHNICOLOR THEORIESCHIRAL HIERARCHIESELECTROWEAK PARAMETERSRADIATIVE-CORRECTIONSQCDHYPERCOLORMODELArticle - Refereedhttps://doi.org/10.1016/S0370-2693(97)00414-04013-4
