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. 14 3 1184 met 1 1 UnsignedMSB4 4 Time tag in seconds of the start of the associated Reporting/Accumulation period. 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. actual_accum 3 7 UnsignedMSB4 4 Actual accumulation period for software counters and energy histograms. gcr_mode 4 11 UnsignedMSB2 2 Galactic Cosmic Ray (GCR) Coincidence mode. =1 Doubles, =2 Triples, =3 Either. sensor_cfg_changed 5 13 UnsignedMSB2 2 Sensor Configuration Changed Flag. =0 config unchanged, =1 config changed. lg_safing 6 15 UnsignedMSB2 2 Maximum Lithium Glass (LG) safing level reached during current reporting period. =0 nominal, =1 seeking, =2 level1_rampdown, =3 level1_waiting, =4 level1_seeking, =5 level2_safing. bp_safing 7 17 UnsignedMSB2 2 Maximum safing level reached during current reporting period for the Borrated Plastic (BP) sensor. =0 nominal, =1 seeking, =2 level1_rampdown, =3 level1_waiting, =4 level1_seeking, =5 level2_safing. log_compression 8 19 UnsignedMSB2 2 Identifies when the log compression data mode has been enabled. The NS flight software uses 32-bit to 16-bit log compression on software counters when the log compression data mode is enabled. See the NS Flight Software document for details on the log compression algorithm. =0 no log compression. =1 log compression enabled. sensor_temp 9 21 UnsignedMSB2 2 Sensor Temperature, External Channel 4 (LVPS). temp_monitor 10 23 UnsignedMSB2 2 LVPS Temperature monitor. lg1_scale 11 25 UnsignedMSB2 2 LG1 singles spectrum scale. lg2_scale 12 27 UnsignedMSB2 2 LG2 singles spectrum scale. bp_scale 13 29 UnsignedMSB2 2 BP singles spectrum scale. tc_scale 14 31 UnsignedMSB2 2 Time-correlated spectra scale. 1 64 1 0 33 128 singles_bp_spectra 1 1 UnsignedMSB2 2 Spectrum is a 64 channel histogram of event energies that arrived as a single event with no time correlation to the other sensors. LG1 is the Lithium Glass 1 sensor. 2 256 1 0 161 512 tc_early 1 1 UnsignedMSB2 2 The time-correlated early spectrum is a histogram of prompt BP events that had a delayed BP event occurring during the early capture window, as defined by commandable software parameters provided in columns EARLY_CAPTURE_START and EARLY_CAPTURE_END of the NS Status EDR, and no additional events in the event set. 3 256 1 0 673 512 tc_late 1 1 UnsignedMSB2 2 The time-correlated late spectrum is a histogram of prompt BP events that had a delayed BP event occurring during the late capture window, as defined by commandable software parameters provided in columns LATE_CAPTURE_START and LATE_CAPTURE_END of the NS Status EDR, and no additional events in the event set. ns_ssp2006167zzz.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
