ANNULUS_RADIUS: 69.915 [deg]

COMMENTS:       Duration ~20 sec. Tripple peaked.  Not seen above 300 keV.

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.
