Notes. Columns 2–5 list the atmospheric parameters (ξ is the microturbulence velocity). The dS and drms distances are described in Sect. 5. Column 8, labelled “Orig. class.”, specifies the classification based on [La/Eu], adopting the criterion suggested by Beers & Christlieb (2005), whereas Col. 9, labelled “New class.”, refers to the star assignment adopted in the present paper (see Sect. 5). The χ2 indicator (Eq. (6) in Sect. 7) quantifies the agreement between the AGB model predictions and the measured abundances of eight heavy elements. Column 11, labelled “Spec”, refers to the spectrograph used (U, H, and HI correspond to UVES, HERMES, and HIRES, respectively). A question mark in the “Bin” column flags a possible spectroscopic binary.

(1)

HD 221170 is an r-process-enriched star not enriched in carbon.
