From 3566 observations 2002 Oct. 12-2004 May 21, mean residual 0".51.
The "original" and "future" barycentric values of 1/a are +0.000010
and -0.000629 (+/- 0.000001) AU^-1, respectively. A somewhat comparable
nongravitational solution, but satisfying 3750 observations with mean
residual 0".49, gives A1 = -0.15 +/- 0.02, A2 = +0.24 +/- 0.01.
