Remarks

11 Jan 2011: Reffert et al. 2011 give a mass range derived from astrometry 100 - 199.6 MJup at the 3 σ level .
The errors on inclination are at the 3 σ level (Reffert et al. 2011) 22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 115 MJ and inclination of 0.5o
Circumstellar disk found at 1.6, 2,1 2.3 and 2.5 microns by Trilling et al (1999). From the disk inclination (46 degrees +4-7 degrees) a planet mass of 1.5 MJ can be infered. Comment by G. Marcy & P. Butler.
