Fractional changes N(Z) = X(Z)/max(X(Z)) of the aggregate number (summed over 15 Gyr) of nova events, nova systems, and the number of nova events per system as a function of the metallicity. There is a significant anti-correlation between all three of these quantities, with the total nova productivity from the highest metallicity systems roughly half that of the lowest. The ejecta mass tracks the event productivity well, particularly for metallicities above Z = 0.01. This figure is an updated version of Figure 5 in Kemp et al. (2022b), including the mass of ejected material.
