HR diagram with 21 Li-rich giants discovered by the Gaia-ESO Survey that have good values of Gaia parallaxes, divided according to metallicity into different panels. The tracks are the same as in Fig. 2. The range of [Fe/H] is given at the top of each panel. Super Li-rich giants with A(Li) > 3.3 dex (in non-LTE) are shown as red circles, and giants with a Li abundance below this are shown as black squares. Typical error bars, ±70 K in T _eff and ±0.12 in log (L/L _⊙), are shown in the bottom right corners of the panels.
