The image including the Vela SNR region is shown in Fig 1. Between position angles p.a.
North is up and east is left.
The present location of the Vela pulsar PSR 0833-45 is marked by the small dark cross. The direction of the proper motion vector of the pulsar is marked by the long arrow pointing to the north-west. The geometric centre of the remnant defined by the circle best-matching the circumference is marked by the big dark cross. Surface brightness increases from light blue over yellow and red to white by a factor of 500. Their symmetry axes intersect between the remnant's centre and the present pulsar position.
