Table 2

Fitting results of the rotational alignment between the Gaia-CRF and the dynamical ephemerides frame, derived from the position differences between Gaia observation and ephemerides.

Notes. The orientation offsets, ϵ_x, ϵ_y, and ϵ_z, and rotational rates, ω_x, ω_y, and ω_z, are given in the upper part of the table, with 1σ uncertainties indicated in parentheses. The lower part lists the correlation coefficients between these parameters.
