Motion of pulsar B0919+06, as sum of the three images made for the pulsar B0919+06 following calibration with J0923+0638, a 12 mJy in‐beam calibrator. The lowest contour level is 1.5 mJy, with increasing steps of a factor 1.4. The resolution is 15 × 10 mas in position angle 0. The peak flux densities at each epoch are: 1994, 4.7 mJy (bottom); 1995, 10.0 mJy (middle); 1996, 6.2 mJy (top).
