On the following pages you will find a comparison between the individual solutions of the analysis centres with respect to the IVS combination. The IVS combination contains the full set of Earth orientation parameters (EOP):
- X-Pole Rate,
- Y-Pole Rate,
- dX and
with respect to IAU 2006/2000A precession-nutation model.
The IVS combination is basically a weighted accumulating of the datum-free normal equation matrices of the analysis centers.
The comparison is embedded into an interactive tool containing data since 1983. The values are smoothed by a moving median. The subset size of the sliding window is ±35 days and is shifted forward each 7 days. The user is free to display the graphics of the individual solution and to choose the time-spans.
The statistic table is updated according to the chosen data set(s).
