• Table 1: Systems with new low-mass companions in the solar neighbourhood. Spectral types are from Reid et al. (1995), except for Gl 173.1, Gl 416, Gl 120.1C, Gl 563.4, and Gl 609.2 which were taken from SIMBAD. They always refer to the combined light of the system. Parallaxes (in milliarcseconds) are taken from (h) the HIPPARCOS catalogue (ESA 1997), (y) the Yale parallax catalogue (van Altena et al. 1995), (s) Söderhjelm 1999, or are photometric parallaxes from (g) the CNS3 (Gliese & Jahreiss 1991) or (r) spectrophotometric parallaxes from Reid et al. (1995) that we approximately correct for the previously unrecognized multiplicity. Program codes are S9 and S12 for the 9.25 and 12 pc volume-limited surveys, C for the unpublished CORAVEL spectroscopic binaries, and L for the spectroscopic and astrometric binaries from the literature. A number of objects belong to multiple samples, and some targets from the nominally volume-limited samples have now been found to lie at larger distances.
• Table 2: Adaptive optics measurement of the new low-mass companions. Gl 268.3 was observed with the Keck adaptive optics system. All other observations were obtained at CFHT with the PUEO adaptive optics system. Periods listed within parentheses are estimated from the observed separation, the distance to the system and its approximate mass. They are uncertain by a factor of approximately 3. 0.5 dex.
