Notes. Columns 2 and 3: J2000 coordinates deduced from the fit of the PdBI 1.3 mm continuum map. Errors on the astrometry are  ≤ 0.05″. Columns 4–6, the spectral type, effective temperature, and the stellar luminosity are those given in Simon et al. (2000). Column 6, CO interferometric papers are: 1 = Piétu et al. (2007), 2 =Simon et al. (2000), 3 = Dartois et al. (2003).
