Notes. The reference epoch for the solution is MJD 55 786.124. Numbers in parentheses are 1σ errors in the last significant digit, while upper limits are evaluated at the 3σ confidence level. The uncertainties reported for ν0 and are the statistical and the systematic uncertainty caused by the position error, respectively.
