Notes to table: the ages and the masses have been obtained from the H-R diagram (Fig. 15). The radii using T_* and L_* from Table 3. The second radius, between brackets, is the result of using alternative temperatures or luminosities suggested in Sect.3.
^a B62-H $\alpha$ 2 is not really a companion, but a nearby star of V1725 Oph, associated to the same globule Barnard 62 (Reipurth & Gee 1986; Weaver & Jones 1992).
^b Companion of CoKu Ser/G1, also known as HBC 666 (Cohen & Kuhi 1979).
