TITLE: GCN/IPN/HUNTSVILLE LOCALIZATION NOTICE_TYPE: Updated (based on the BATSE-LOCBURST location) NOTICE_DATE: Thu May 6 01:14:40 GMT 1999 TRIGGER_NUM: 7548 GRB_DATE: 99/05/05 GRB_TIME: 07:51:07.51 UT BACO_RA: 230.27d {+15h 21m 05s} (J2000) BACO_DEC: -55.21d {-55d 12' 43"} HUNT_RA: 231.27d {+15h 25m 04s} (J2000) HUNT_DEC: -51.26d {-51d 15' 32"} HUNT_ERR: 2.19 [degees radius, statistical only] B_H_DELTA: 4.00 [deg] HUNT_SC_AZ: 146.19 [deg] HUNT_SC_EL: -51.85 [deg] {Zen_angle=141.85} SUN_POSTN: 41.93d {+02h 47m 43s} +16.16d {+16d 09' 25"} (Current) SUN_B_DIST: 140.42 [deg] MOON_POSTN: 276.06d {+18h 24m 15s} -19.98d {-19d 58' 57"} (Current) MOON_B_DIST: 49.12 [deg] ANNULUS_RA: 145.0174d {+09h 40m 04s} (J2000) ANNULUS_DEC: -7.3548d {-07d 21' 16"} ANNULUS_RADIUS: 78.261 [deg] ANNULUS_WIDTH: 0.095 [deg] (Total width) COMMENTS: Duration ~15 sec. Single pulse. 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.
