Notes. Column 1: centimeter continuum components used for the proper motion calculation. Column 2: observational epochs. Columns 3 and 5: centroid position obtained from a two-dimensional Gaussian fit, and Cols. 4 and 6: positional uncertainties of the Gaussian fits as specified in Appendix A. Positions at the first epoch are obtained from Table 2 of Cyganowski et al. (2011). Columns 7 and 8: (relative) proper motion components in the east-west and north-south directions, respectively. Columns 9 and 10: magnitude of the proper motion and its position angle (east of north).
