GCN NOTICES Three WAKEUP alerts (alerts 1756, 1757, 1758) are due to relatively high sigma value of the burst (and thus small position error) as seen by ibas monitors. Unfortunately, the differences in grb positions computed by different monitors were slightly above the threshold level (function of grb sigma value), so the positions from all monitors which triggered were grouped by ibasalertd into 3 groups meaning 3 separate events => the result was 3 WAKEUP alerts for the same event. See also notes for IBAS alerts 1979 and 1980 on this page. |
