From 840 observations 2001 Aug. 24-2004 May 21, mean residual 0".90.
The "original" and "future" barycentric values of 1/a are +0.000042
and -0.000702 (+/- 0.000001) AU^-1, respectively. A somewhat comparable
nongravitational solution, but satisfying 860 observations with mean
residual 0".79, now gives A1 = +1.13 +/- 0.05, A2 = -0.05 +/- 0.04.
