Comparison among the different simple stellar population libraries included in GalaPy: classic BC03 (blue), PARSEC22 without line emission (green), PARSEC22 with line emission (red). Linestyles refer to different metallicity as reported in legend. In all panels the approximate age of the stellar population is reported. In the top two panels we show SSPs from young stellar populations for whom the PARSEC22 models include the contribute of synchrotron (green models) as well as that of nebular emission (red models).
