Notes. Numbers in boldface refer to the comparison with JVLA values. We also report the relative rotations, obtained by comparing antenna tables for consecutive epochs, and the reference antennas used for the phase calibration.

^(a)

Final rotation to apply to obtain the absolute EVPA orientation.

^(b)

Relative rotation obtained by comparing antenna table of two consecutive epochs.

^(c)

PT = Pie Town, KP = Kitt Peak, OV = Owens Valley.
