\caption{EVN rms astrometric errors (in $\mu$as) for a relative source separation
$\delta -\delta _0= 1\degr$. Individual astrometric error contributions from station
coordinate and wet troposphere uncertainties are given separately along with the
total astrometric errors when all model parameters are perturbed together.
