========================================================================== BAT GROUND-DETECTED GRB DATA PROCESSING REPORT (This burst occurred during telescope slew) Process Script Ver: batgrbproduct v2.46 Process Start Time: Mon Mar 23 14:19:40 EDT 2015 Host Name: bat1 Current Working Dir: /local/data/bat1/alien/Swift_3rdBATcatalog/event/batevent_reproc/GRB090823 ====================================================================== Trigger: 00036390 Segment: 005 BAT Trigger Time: 272736676.8 UTC: 2009-08-23T16:11:11.777 [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: 128.701911074135 Dec: 60.6029026479423 [deg; J2000] { 08h 34m 48.5s , +60d 36' 10.4" } +/- 2.06054729292 [arcmin] (estimated 90% radius based on SNR) SNR: 10.830004702 Angular difference between the GCN position and this refined position is 3.436 arcmin Partial Coding Fraction: Unavailable because the burst occurred during slew. Duration T90: 25.6000000238419 +/- 1.6 Measured from: 0 to: 25.6 [s; relative to TRIGTIME] T50: 14.4000000357628 +/- 1.6 Measured from: 3.2 to: 17.6 [s; relative to TRIGTIME]
