Notes. For the proper motion results and the goodness-of-fit, 
, the results for a fixed parallax π = 0.1 and for the fitted parallax, πfit, are listed. The positions listed are for the indicated MJDs (epochs with the best S/N). For S1 the positions were measured relative to the phase calibrator while the positions of the remaining sources were measured relative to S1.
