Notes. (a) Integrated spectral types, J magnitude, and log[ $L_{\rm x}/L_{\rm bol}$] from Riaz et al. (2006). Distance is spectroscopic distance from Riaz et al. (2006) if not otherwise indicated. The uncertainty in the spectroscopic distances is 37%. (b) Epoch of $z^\prime $-band observations, for which the astrometric properties of the multiple systems are derived. (c) Binary/multiple system observed with AstraLux, see Tables 2 and 3 for properties. (d) Parallax distance from Hipparcos (Perryman & ESA 1997). (e) Parallax distance from Reid et al. (2004). (f) Parallax distance from van Altena et al. (1995). (g) This is one component of a wide ( $\rho=19.9\hbox{$^{\prime\prime}$ }$, epoch 2001) visual double-star system (Mason et al. 2001). The system is therefore not included in the statistical analysis. (h) This is the secondary component of a wide multiple system with the G-type primary star NLTT 4704. The system is therefore not included in the statistical analysis. (i) This is the primary component of a Hipparcos visual double system, with the secondary component outside our field of view at $\rho=105.0\hbox{$^{\prime\prime}$ }$ (epoch 1991.25, Dommanget & Nys 2000). The system is not included in the statistical analysis. (j) The target J06061342-0337082 has spectroscopic distance 57 pc and is therefore not included in the multiplicity analysis. (k) The star is part of a wide binary system with the white dwarf GJ 841 B (Holberg et al. 2002) and is therefore not included in the statistical analysis. (l) The star is part of a wide binary system with the primary G8V star HD 218860A (Torres et al. 2006) and is therefore not included in the statistical analysis. (m) Epoch refers to the $i^\prime $-band observation, from which astrometric properties were derived. (n) The star is part of a multiple system in which the K6V star (Torres et al. 2006) Gl 898 is the primary (Dommanget & Nys 2000). The star is therefore not included in the statistical analysis. (o) The star is part of a wide binary system (Mason et al. 2001) and is therefore not included in the statistical analysis. (p) The star is part of a common proper motion system (Mason et al. 2001) and is therefore not included in the statistical analysis.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
