Remarks

11 Jan 2011: Reffert et al. 2011 give a mass range derived from astrometry 24.6 - 130.7 MJup at the 3 σ level.
The errors on inclination are at the 3 σ level (Reffert et al. 2011) 5 Sep 2010: The former mass of 25 MJ has now been revised to 101.8 MJ (Sahlmann et al. 2010) 03 Nov. 2008: Planet or bown dwarf? The boundary between these categories is not not clear (Deleuil et al 2008).
