COMMENTS: This notice is based on 1 1.024-sec samples of the light curve. COMMENTS: This report is based only on the BATSE-Original and IPN COMMENTS: information as input. There is no Huntville input COMMENTS: at this early stage of processing. Questionable localization. COMMENTS: Burst duration ~5 sec. 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 BACODINE 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.
