A set is defined as all data with time stamps corresponding to a given Earth day. Additional details are contained in the EDR SIS document. 7 1 346 met 1 1 UnsignedMSB4 4 Time tag in seconds of the gamma-ray burst trigger. orbit_number 2 5 UnsignedMSB2 2 Orbit number is a unique identifier for a given orbit of the MESSENGER spacecraft around Mercury. Orbit number is defined as starting at apoherm and is calculated using the MET value and the appropriate SPICE kernels. Orbit numbering does not start until MESSENGER performs the Mercury orbit insertion. Until that time the value for orbit number is 0. gamma_ray_mode 3 7 UnsignedMSB2 2 Gamma Ray mode. =0 RAW, =1 PROCESSED. bp_ch_upper_limit 4 9 UnsignedMSB2 2 The highest BP channel that will be used as part of the source of the Gamma-Ray burst BP counts. trig_boxcar_accum 5 11 UnsignedMSB4 4 Number of counts in the running box car accumulator at the time of the trigger. Box car length is 164 events. burst_threshold 6 15 UnsignedMSB2 2 Burst lower pulse threshold for trigger in raw ADC units. post_trigger_counts 7 17 UnsignedMSB2 2 Number of post trigger counts. 1 164 1 0 19 328 gamma_ray_burst 1 1 UnsignedMSB2 2 Collection of 164 (1-sec) BP counts. ns_gab2012129zzz.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
