Notes. Columns are the reference number in this work, the target name, the star-forming region, the distance d, the spectral type, the projected separation of bright visual companions, the stellar luminosity L*, the mass M*, the age t, the polarized-to-star light contrast δpol/star (see Appendix C), the millimeter flux Fmm (at wavelengths given by the apex numbers), and the reference for Teff (numbers) and Fmm (letters). Only bright companions (>1% in flux of the primary) are listed here (a complete census can be found in Appendix A). Stellar properties refer to the primary object (see Sect. 2). The full name of each target is shown in Table B.1.
