Age estimates for HD 52265. Columns CaII, L_X, Li and gyrochronology give empirical estimates based on the index (circle), the lower limit from X-luminosity (upwards triangle), the upper limit from lithium surface abundance (downwards triangle) and, the gyrochronology (diamonds). The column HRD inversion shows estimates based on inversion of isochrones with circles for Padova isochrones and diamonds for BaSTI isochrones, full symbols for Bayesian methods, and empty symbol for χ²-minimisation, see text. The column seismic shows the seismic determination for à la carte models of case 6 (Table 3 and Fig. 4)
