A set is defined as all data with time stamps corresponding to a given Earth day. 11 Carriage-Return Line-Feed Comma 10 1 met 1 ASCII_Integer Time tag in seconds of the gamma-ray burst trigger. cmd_utc_date 2 ASCII_String UTC date in YYYY-MM-DD format derived from the MET using SPICE kernels. cmd_utc_time 3 ASCII_String UTC time in HH:MM:SS.SSS format derived from the MET using SPICE kernels. cmd_utc_sec 4 ASCII_String UTC time as seconds since 00:00:00 derived from the MET using SPICE kernels. orbit_number 5 ASCII_Integer 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 6 ASCII_Integer Gamma Ray mode. =0 RAW, =1 PROCESSED. bp_ch_upper_limit 7 ASCII_Integer The highest BP channel that will be used as part of the source of the Gamma-Ray burst BP counts. trig_boxcar_accum 8 ASCII_Integer Number of counts in the running box car accumulator at the time of the trigger. Box car length is 164 events. burst_threshold 9 ASCII_Integer Burst lower pulse threshold for trigger in raw ADC units. post_trigger_counts 10 ASCII_Integer Number of post trigger counts. 1 164 1 0 gamma_ray_burst 1 ASCII_Integer Collection of 164 (1-sec) BP counts. ns_cdr_gab2012144zzz.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
