  Chandra images of the Crab Nebula resolve the detailed structure of its
"inner ring", possibly a termination shock where pulsar-accelerated
relativistic particles begin to emit X radiation. Analysis of these images
finds that the center of the ellipse-presumably a circular ring in
projection-lies about 0.9" (10 light-days at 2 kpc) from the pulsar's image, at
a position angle of about 300{\deg} (East of North). This analysis also
measures properties of the ellipse: The position angle of the semi-major axis
is about 210{\deg} (East of North); the aspect ratio, 0.49.
  In a simple-albeit, not unique-de-projection of the observed geometry, a
circular ring is centered on the axis of symmetry of the pulsar wind nebula.
This ring is not equatorial but rather lies near +4.5{\deg} latitude in
pulsar-centered coordinates. Alternative geometries are briefly discussed.
