DATA_SET_DESCRIPTION
Data Set Overview
   ====================
This data set describes the counting rate data from detectors D1 and D2
in the Cosmic Ray System (CRS) electron telescope (TET) on Voyager 2 during
the Saturn encounter. The D1 detector nominally responds to electrons with
kinetic energies above approximately 1 MeV, and the D2 detector, above
approximately 2.5 MeV (see detector description for details).

Note that the instrument is saturated near the maximum of counting
rate of approximately 50,000 counts/sec. The following time intervals
in 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 corrected
for deadtime according to the formula in the DATA_SET_OR_INST_PARM_DESC:
{corrected rate} = {uncorrected rate/(1+deadtime*{uncorrected rate}).

Confidence Level
    =================
Each data point represents a six-second accumulation, so that the
statistical uncertainty is obtained according to Poisson statistics by
taking the square root of one sixth of the counting rate.  However,
larger uncertainties are associated with the conversion from counting
rate to flux (see the DATA_SET_OR_INST_PARM_DESC)
