Notes. Differences between our series and the IVS ones are characterized in terms of the weighted rms, reduced chi-squared and relative slope for each of the five EOP, i.e., the two polar motion components (xp, yp), the daily rotation UT1, and the two nutation offsets (X, Y). Median values of the EOP uncertainties resulting from our ICRF3 K band analysis solution are also indicated in the table for comparison.
