References: Spectral types are obtained either from SIMBAD or one of the cited papers, if a more accurate classification is available in the literature. and (log g) list the temperature and surface gravity which we used for the Kurucz atmosphere models. V-band magnitudes and IRAS 12 m fluxes are taken from the SIMBAD database. KK Oph shows variability in the visual. PDS 144 is not resolved by IRAS; its V-band fluxes were given by Perrin et al. (2006). Stellar ages: (1) Song et al. (2001), (2) Wyatt et al. (2005) and references therein, (3) Dunkin et al. (1997) and references therein, (4) mean age of the  Pic moving group as given in Zuckerman & Song (2001), (5) Catala et al. (2007), (6) Quast et al. (2000), (7) e.g. D'Angelo et al. (2000), (8) Carmona et al. (2007). Errors in the age determinations are quite heterogeneous, depending on the cited work. Distances are taken from (9) Hipparcos parallax, (10) uncertain Hipparcos parallax, (11) Wyatt et al. (2005), (12) The Hipparcos parallax was recently removed from SIMBAD and is likely not firm, (13) Sylvester et al. (1996), (14) van den Ancker et al. (1998), (15) Quast et al.

Note on the multiplicity of HD 155 555: Although the SB components are not spatially resolved, we label them as A and B, since this naming convention existed already in the literature.
