Notes. The numbers k and l provide the number of rejected stars and the number of stars remaining in the sample for each baseline solution. The σ values indicate the formal errors of the parameter estimates from the baseline solution for each scenario. Final uncertainties are obtained by multiplying the σ values by $\sqrt{Q / n}$ $\sqrt {Q/n}$ . Units are in milliarcseconds for ϵ_X(T), ϵ_Y(T), and ϵ_Z(T) and milliarcseconds per year for ω_X, ω_Y, and ω_Z.
