Table 1: Adopted rms errors for the source coordinates, VLBA station coordinates and Earth Orientation Parameters in our Monte Carlo simulations.
Table 2: Dry and wet tropospheric zenith path delays ( $\tau _{\rm dtrp}$ and $\tau _{\rm wtrp}$ ) at the VLBA stations along with the adopted rms errors $\Delta \tau _{\rm dtrp}$ and $\Delta \tau _{\rm wtrp}$ in our Monte Carlo simulations.
Table 3: VLBA rms astrometric errors (in $\mu$ as) for a relative source separation $(\alpha -\alpha _0)\cos\delta_0 = 1\hbox{$^\circ$ }$ . Individual astrometric error contributions from calibrator position, Earth orientation parameter, station coordinate, and dry and wet troposphere uncertainties are given separately, while the last two lines indicate the total astrometric errors when all model parameters are perturbed together.
Table 4: VLBA rms astrometric errors (in $\mu$ as) for a relative source separation $\delta -\delta _0= 1\hbox {$^\circ $ }$ . Individual astrometric error contributions from calibrator position, Earth orientation parameter, station coordinate, and dry and wet troposphere uncertainties are given separately, while the last two lines indicate the total astrometric errors when all model parameters are perturbed together.
