AbstractIt has been suggested that the Crab pulsar's proper motion is aligned with the symmetry axis of the pulsar wind nebula. We have revisited this question, examining >6 years of F547M WFPC2 chip 3 images to obtain a best-fit value of μ* = 14.9 ± 0.8 mas yr -1 at P.A. 278° ± 3°.At 26° ± 3° to the nebula axis, this substantially relaxes constraints on the birth kick of this pulsar. Such misalignment allows the momentum to be imparted over ∼1 s timescales. © 2006. The American Astronomical Society. All rights reserved.
