HIP 70849: added brown dwarf companion
HD 213240: added fluxes for secondary

Lodieu et al. (arXiv 2014) http://arxiv.org/abs/1408.1208
HD 126614: added inner and outer binaries.
Note that WDS designations and literature disagree as to which component is B and which is C.

Inner binary (HWD 1) was discovered by Howard et al. (2010), from which the mass and V-magnitude are taken.
The system was confirmed by Ginski et al. (2012), which is used for separation and position angle.

Outer binary (LDS 4465) is a known common proper motion pair.
Spectral type and fluxes are taken from Lodieu et al. (arXiv 2014), who confirm physical association.
Separation and position angle taken from the WDS.
