Fig. A.1


Revised proper motions of VLA4A and VLA4B. This figure is identical to Fig. 2 of CG08 with additional data. Reference positions are 03:29:03.732 31:16:03.974 (J2000) for VLA4A, and 03:29:03.7566 31:16:04.000 (J2000) for VLA4B. Dotted gray lines display CG08 proper motions based on their measurements (gray points). Solid blue lines are our best linear fit to all VLA radio data including the positions of Tobin et al. (2016). Vertical blue dashed lines identify the weighted date of CALYPSO observations (2012.43).
