Notes. Description of Col. 1: Literature: E(B − V) given by (a) Forbes (1981), (b) Johnson (1962), (c) Pérez et al. (1987) and Rebull et al. (2002), (d) Mayne & Naylor (2008); S.T.: mean results based on spectral type (see Sect. 3.1); ZAMS: main sequence fitting (see Sect. 4); AVMap: visual extinction, from Dobashi et al. (2005) map, converted into E(B − V) by adopting normal RV.
