Note
Observatories: CFS = Coudè Feed Spectrograph at Kitt Peak Coude Feed Telescope
SB9: This is the orbit as it appears in the original paper. However, we do
obtain a better plot if one replaces the corresponding elements with T=44464.2;
omega=73deg and K1=30.4km/s. At least, with those values, the plot looks
close to the one in the paper. In any case, the the orbit is very poor.
