Notes. Columns 1 to 5 list the name of the star, stellar effective temperature, distance, age, and mass accretion rate. Unless otherwise indicated, the stellar temperatures, distances and ages are taken from Montesinos et al. (2009). Accretion rates (on log scale) are taken from Paper II. Columns 6 to 8 refer to possible stellar companions. Column 6 lists their angular distance and spectral type, Col. 7 their difference in K magnitude (Ks for ∗1, K′ for ∗2 and Hipparcos Hp for ∗3), and Col. 8 the corresponding references. HD 34700 is a triple visual system, the brightest object of which is a spectroscopic binary (1). HD 141569 is a triple system (3). Columns 9 to 13 list the SED classification from the Meeus et al. (2001) scheme, the photometric band according to the shortest wavelength where the IR excess is apparent, the intrinsic near-IR colour excess, and the IRAS colours. Columns 14 to 16 list the dust temperature, β value, and disk mass (on log scale). These were obtained from the fluxes at 1.3 mm, except for HD 34700, V1686 Cyg, RY Tau and LkHa 234 (see Table A.2).References. AManoj et al. (2006), BAlonso-Albi et al.
