Parameter Value        
$\chi ^{2}$ 855.8        
d.o.f. 841        
Radial velocity rms (m s-1) 4.2        
Astrometry rms (mas) 0.9        
Note: Planet d's inclination and longitude of the ascending node were tied to those of planet b. The orbital parameters are osculating and valid at HJD 2 452 490.0. The coordinates ($\xi$ and $\eta$) are relative positions in the reference frame of the constraint plate. To convert to the RA - Dec reference frame, the coordinates should be rotated about the inverse of the determined roll angle ( $26.07\hbox{$^\circ$ }^{~+0.04\hbox{$^\circ$ }}_{~-0.04\hbox{$^\circ$ }}$). The $\chi ^{2}$ and rms shown are for the best-fit model.
