SC_EV_TIME 2 9 UnsignedMSB8 8 Spacecraft time at the middle of the pixel, in ticks. SC_EV_TIME_FINE 3 17 UnsignedMSB2 2 Fine time portion of spacecraft time at the beginning of the pixel, units of 65536ths of a second. CEB_TIME 4 19 UnsignedMSB8 8 ms Clock count from the GRS Common Electronics Box at the beginning of the pixel. UTC 5 27 ASCII_String 23 SC_EV_TIME converted to UTC, stored as yyyy-mm-ddThh:mm:ss.sss. GRS_PIXEL_NUMBER 6 50 UnsignedMSB4 4 Sequential counter of accumulation intervals, starts with one as grs orbit begins. Special case on reboot when the the CEB is in orbit 0, pixel 0. 0 GRS_ORBIT_NUMBER 7 54 UnsignedMSB4 4 Sequential counter of orbits from GRS CEB boot. 0 ODY_ORBIT_NUMBER 8 58 UnsignedMSB4 4 Orbit number common to all instruments aboard Odyssey. This orbit number is incremented by one as the spacecraft passes through the orbital descending node. 0 BAD_CODE 9 62 UnsignedMSB4 4 If non-zero, the data has been flagged bad. Definitions in bad_code.txt. COUNTER 10 66 UnsignedMSB4 4 A spectra can come down in up to 4 packets. Each packet has its own counter. This counter is the combination of all eight possible counters, four bits for each. PROFILE_COUNT 11 70 UnsignedMSB2 2 Number of 4-scalar element sets that are in the profile array. PROFILE_SERIES 1 2048 4 0 Series of summed counts of gamma events in four energy ranges. The nominal summing period is 32 milliseconds. 72 32768 LLD 1 1 SignedMSB4 4 All counts above the LLD energy. -1 LLD_L1 2 5 SignedMSB4 4 Counts in the LLD to L1 energy range. -1 L1_L2 3 9 SignedMSB4 4 Counts in the L1 to L2 energy range. -1 L2_L3 4 13 SignedMSB4 4 Counts in the L2 to L3 energy range. -1 profile_data_20031021.lbl 0 PDS3 PDS3 label Carriage-Return Line-Feed
