[X/Fe] vs [Fe/H] for Zr, Ba, and La for the model with Rubele et al. (2018) SFH and increased MNS r-process production at low-metallicity (see Eq. (4)), adopting different IRV distributions (see Table 1). Blue lines represent models adopting the reference IRV distribution (R150, thick solid lines), R300 distribution (thin dashed), DIS2 distribution (thin dash-dotted), and DIS3 distribution (thin dotted). Cyan shaded regions are predictions for the model with the DIS2 distribution accounting for observational uncertainties (i.e. synthetic model). Data are as in Fig. 5.
