Notes. Spectral types are estimated from the (g - i) colour relation of Covey et al. (2007) and distances from the photometric parallax from Davenport et al. (2006). Temperatures are estimated by a greybody fit to the 250, 350 and 500 $\mu$ m fluxes and the upper limits of 140 mJy at 160 $\mu$ m, and 105 mJy at 110 $\mu$ m with a fixed $\beta= 0.5$ (Wyatt et al. 2005). Masses are calculated using the standard technique with a mass absorption coefficient $\kappa = 1.7$ cm² g^-1 at 850 $\mu$ m (Sheret et al. 2004).
