[X/Fe] vs [Fe/H] for n-capture elements for the model with Rubele et al. (2018) SFH and low-mass AGB yields by Choplin et al. (2022, 2024b), adopting different IMFs. Blue lines represent models adopting the reference Kroupa (2001) IMF (thin dash-dotted), Kroupa et al. (1993) IMF (thin dashed) and a modified Kroupa et al. (1993) IMF with steeper high-mass end slope (top-light IMF, thick solid). Cyan shaded regions are predictions for the model with top-light IMF accounting for observational uncertainties ('synthetic model'). Data are as in Fig. 5.
