| Data Set Abstract |
The archived data consist of count
rates from the sum of two hemispherical
detectors covering 4 pi steradians and
operating continuously. The detectors
are 3 mm thick CsI scintillators
coupled to photomultiplier tubes. The
nominal energy range is 25-150 keV, but
the below table should be consulted to
find the accurate thresholds for any day
of the mission. Although the prime
objectives of this investigation are the
study of solar and cosmic x- and
gamma-ray bursts, it should be noted
that the experiment is also sensitive
to solar protons and electrons. The
former deposit energy directly in the
scintillator if they are energetic
enough, while the latter may produce
x- radiation locally by bremsstrahlung.
Thus although the counting rates are
generally stable at about 500 c/s over
the long term, there are periods of
weeks to a month or so when the rates
increase considerably due to particles.
Examples may be found in March 1991
(solar protons) and February 1992
(particles in the Jovian magnetosphere).
The time resolution of the data takes
on one of four values depending on the
telemetry rate and instrument operating
mode: 0.25, 0.5, 1, or 2 seconds. |
