Fig. 7.
One of the acceptable fits of chemical enrichment in NGC 5044. Yields of SNcc (magenta) and SNIa (blue) are used for the fit with Eq. (5). The adopted IMF power-law index is 2.35 (Salpeter) and the initial metallicity of the stellar population is 0.02 (solar). N/Fe and yields of AGBs are not included in the fit, but are shown for comparison. The SNIa fraction 
is (31.9 ± 1.6)%.
