Notes. For scenarios “41” not including the January 2020 positions, iterations 9 to 34 were used for calculation, whereas for scenarios “55” including the January 2020 positions, iterations 12 to 47 were considered. For derivation of values MEs the last 10 iterations were rejected because the formal errors of the rotation parameters increase substantially if only a few stars are available for calculation. Units are in milliarcseconds for ϵX, ϵY, and ϵZ and milliarcseconds per year for ωX, ωY, and ωZ.
