Notes. Numbers in parentheses are 1σ errors in the last significant digit. Upper limits are evaluated at 3σ confidence level. The uncertainties have been scaled by a factor to take into account a reduced χ2 of the best-fit model larger than 1. The uncertainties quoted in the estimates of ν and  do not include the systematic errors due to the positional uncertainty.

(a)

Time interval covered by the presented solution.

(b)

Reference epoch for the timing solution.
