Notes. Teff, Nbelow, Nabove, Lgran, and HP are evaluated as time averages during the kinematic phase of the simulations, as detailed in the text (see Sect. 2.3). The last three rows display the best stellar proxies to our models in terms of Teff and log 𝑔 from the Gaia benchmark stars of Heiter et al. (2015; see Sects. 2 and 4 for more details).
