This IPN localization is preliminary.  The "total width" of the annulus
was selected to include all known uncertainties and systematics.  The final
analysis will reduce this width.  All follow-up queries should be addressed to
Kevin Hurley (UC Berkeley, khurley@sunspot.ssl.berkeley.edu).

The center of the IPN annulus is tabulated below along the segment
that intersects the Huntsville error circle.  The Distance column is
the sky-angle distance between the Huntville location and the sampled position
on the arc segment.  The position of maximum probability plus
the 1-, 2-, & 3-sigma containment probabilities (statistical+systematic)
are marked.
