========================================================================== BAT GROUND-DETECTED GRB DATA PROCESSING REPORT (This burst occurred during telescope slew) Process Script Ver: batgrbproduct v2.46 Process Start Time: Tue Nov 11 09:09:37 EST 2014 Host Name: bat1 Current Working Dir: /local/data/bat1/alien/Swift_3rdBATcatalog/event/batevent_reproc/GRB090306B ====================================================================== Trigger: 00031369 Segment: 001 BAT Trigger Time: 258073644.0 UTC: 2009-03-06T23:07:19.447 [includes UTCF correction] Where From?: Ground analysis (best_duration.txt) NOTE: BAT trigger time for ground-detected burst during slew is the T100 start time. Refined Position: [ source = BAT mosaic image ] RA: 231.205735469434 Dec: -6.96613028439822 [deg; J2000] { 15h 24m 49.4s , -6d -57' -58.1" } +/- 0.557460176597 [arcmin] (estimated 90% radius based on SNR) SNR: 70.1014245266 Angular difference between the GCN position and this refined position is 0.197 arcmin Partial Coding Fraction: Unavailable because the burst occurred during slew. Duration T90: 21. +/- 1. Measured from: 1 to: 22 [s; relative to TRIGTIME] T50: 8. +/- 1. Measured from: 4 to: 12 [s; relative to TRIGTIME]
