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 2 288 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. 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 lg1_gcr_spectrum 1 1 UnsignedMSB2 2 LG1 Galactic Cosmic Ray spectrum. 2 64 1 0 161 128 lg2_gcr_spectrum 1 1 UnsignedMSB2 2 LG2 Galactic Cosmic Ray spectrum. ns_gcr2012144zzz.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
