Equation (1) should read:

$a_2=a-a_1=4.114 \pm 0.181~U.A. = 615.2 \ 10^6~{\rm km}\ \ \ \ (1)$

The error estimate in the paper ($\pm 0.031$) referred to the quantity a1 instead of a2. This was a typing mistake, so that the other error estimates (e.g. on the mass ratio) are correct.

Our thanks go to Dr. Roger Griffin for drawing our attention to this mistake.
