DATA_SET_DESCRIPTION |
Data Set Overview :This data set describes the counting rate data from detectors D1 and D2in the Cosmic Ray System (CRS) electron telescope (TET) on Voyager 2 duringthe Saturn encounter. The D1 detector nominally responds to electrons withkinetic energies above approximately 1 MeV, and the D2 detector, aboveapproximately 2.5 MeV (see detector description for details). Note that the instrument is saturated near the maximum of countingrate of approximately 50,000 counts/sec. The following time intervalsin this data set contain saturated data: D1: 1981-08-26 01:37 --> 1981-08-26 02:13 1981-08-26 05:15 --> 1981-08-26 05:51 D2: 1981-08-26 02:32 --> 1981-08-26 03:08 1981-08-26 04:24 --> 1981-08-26 04:47 When data are near saturation, the counting rates should be correctedfor deadtime according to the formula in the DATA_SET_OR_INST_PARM_DESC:{corrected rate} : {uncorrected rate/(1+deadtime*{uncorrected rate}).

CONFIDENCE_LEVEL_NOTE |
Confidence Level :Each data point represents a six-second accumulation, so that thestatistical uncertainty is obtained according to Poisson statistics bytaking the square root of one sixth of the counting rate. However,larger uncertainties are associated with the conversion from countingrate to flux (see the DATA_SET_OR_INST_PARM_DESC) Data Coverage : Filename Records Start Stop ---------------------------------------------------------------------- Volume ID: VG_1601 D1D2.TAB 2705 1981-08-24T16:01:36.000Z 1981-08-30T21:58:24.000Z Missing Data Flag : Any data column whose value is -9.999e+10 is a missing data value.
