A study is presently conducted of the colors of elliptical galaxies in nine distant clusters, with reference to theoretical models for evolutionary population synthesis. The admissible ranges of the relevant cosmological parameters are inferred.STAMPAenArticle10.1086/1727672-s2.0-0041470518https://ui.adsabs.harvard.edu/abs/1993ApJ...410..499B/abstracthttps://api.elsevier.com/content/abstract/scopus_id/00414705181993ApJ...410..499B
