Caption: Figure 3.

ALMA Band 7 intensity contours (in green) of the nebula close to the Vela pulsar (see Figure 1) superimposed on the HST/ACS, Chandra/HRC, Gemini/GeMS-GSAOI, and VLT/NACO images of the field, top left to bottom right. In all panels, the angular dimension is 10″ × 10″ and the arrow indicates the pulsar. The time baseline between the Gemini, VLT, and ALMA observations (∼3 years), together with the spatial resolution (0.″8) and astrometry accuracy (0.″123) of the Band 7 image, are not sufficient to appreciate a relative angular displacement of the nebula comparable to that predicted for the pulsar (≈0.″2) as a results of its proper motion.
