Best fits to the sample stars of Table 4 using the AGB models computed in this work (Table 2). The upper panels compare the [X/Fe] ratios as a function of the charge number Z, while the lower panels gives the deviations between the model and observation. The three best models are shown in black (lowest ), grey (second lowest ), and light grey (third lowest ). The dilution factor f_dil (Eq. 5) and smallest value are indicated. The abundance data are taken from the SAGA database (Suda et al. 2008), complemented with a few recent observations (see Table 4).
