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.
