Notes.

^(a)

Stars names, following the nomenclature of Hernandez et al. (2007);

^(b)

values of the mass accretion rates derived from the U-band excess emission;

^(c)

width of the Hα line at 10% of the peak;

^(d)

values of the Ṁ_acc obtained using the empirical relation which involves the Hα width at 10% of the peak (Natta et al. 2004);

^(e)

pseudo-equivalent width of the Hα line.
