Notes. All epochs are in RJD; rms is the rms of one observation of unit weight. The error of epoch is shorter for a reference epoch close to the centre of the interval covered by data. To facilitate comparison of the first solution with the remaining two, we also provide corresponding recalculated epochs: RJD 54 386.0, RJD 54 383.6, and RJD 54 377.4.
