Notes. Stellar parameters L_∗, R_∗, M_∗, ST and extinction are taken from Spezzi et al. (2008), unless explicitly noted.

^(a)

Coordinates from the 2MASS catalogue.

^(b)

Luminosity computed by integrating the Spectral Energy Distribution between 1 and 70–100 μm, using 2MASS and Spitzer measurements corrected for extinction.

^(c)

K-band magnitude from 2MASS.

^(d)

Mass estimate from D’Antona & Mazzitelli (1997) evolutionary tracks (see Spezzi et al. 2008).
