Comparison between our LDB age and the age estimated using other techniques. Left: sges derived from the isochrone fitting technique. The ages come from: Gaia Collaboration (2018b; blue diamonds), Bossini et al. (2019; purple squares), and Mermilliod (1981; gray circles). Middle: ages derived from the Pre Main-Sequence isochrone fitting technique. Orange diamonds represent PMS isochrone fitting ages: the Pleiades, BPMG, THMG and 32 Ori MG, Bell et al. (2013, 2014, 2015); and IC4665, Cargile & James (2010). Brown squares are the rest of PMS isochrone fitting ages: NGC 1960, Bell et al. (2013); IC 4665, Manzi et al. (2008); NGC 2547, Naylor & Jeffries (2006); IC 2602 and IC 2391, Stauffer et al. (1997); Alpha Persei, Prosser (1992); the Pleiades, Stauffer et al. (1995b); Blanco 1, Cargile et al. (2009); BPMG and THMG, Torres et al. (2006); and 32 Ori MG, Mamajek (2007). Right: LDB ages derived from previous works. See the references in Table 1, its legend, and Sect. 2.
