A set is defined as all data with timestamps corresponding to a given Earth day. Additional details are contained in the EDR SIS document. 4 0 14 met 1 1 UnsignedMSB4 4 Time tag in seconds associated with the counters in the time-correlated counters packet. 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. tc_early_counter 3 7 UnsignedMSB4 4 Summation of all channels of early time-correlated spectra. tc_late_counter 4 11 UnsignedMSB4 4 Summation of all channels of late time-correlated spectra. ns_tcc2006068zzz.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
