There is one row for each sample. 7 2 4124 512 1 0 1 2048 Accepted Spectrum 1 IEEE754LSBSingle 4 The total number of accepted gamma-ray counts per 32 seconds. 512 1 0 2049 2048 Rejected Spectrum 1 IEEE754LSBSingle 4 The total number of rejected gamma-ray counts per 32 seconds. Deadtime 1 4097 IEEE754LSBSingle 4 The fractional deadtime is the fractional amount of time per 32 seconds that the LP-GRS instrument is busy processing data. Overload 2 4101 IEEE754LSBSingle 4 The total number of counts per 32 seconds for events that deposit more than 2.55 MeV in the anticoincidence shield scintillator. GRS_Tempature 3 4105 IEEE754LSBSingle 4 Celsius LP-GRS Housing Temperature. Earth_Received_Time 4 4109 IEEE754LSBSingle 4 The time that the collected data is received at Earth, or in the case of delayed data, the time when the data would have been received at Earth had it been delivered in real time. The units are day of year since 1 January 1998. To determine the spacecraft acquisition time from the ERT, a 2 second spacecraft buffering time and 1.28 second Moon to Earth travel time needs to be subtracted from the ERT. Spacecraft_Altitude 5 4113 IEEE754LSBSingle 4 km Spacecraft height above the lunar surface. Subspacecraft_Latitude 6 4117 IEEE754LSBSingle 4 degree The latitude of the subspacecraft point at the time of data collection. Subspacecraft_Longitude 7 4121 IEEE754LSBSingle 4 degree The longitude of the subspacecraft point at the time of data collection. 1999_090_grs.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
