Low-Energy Time-Averaged Flux Data

NSSDCA ID: PSFP-00247

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1977-09-07 to 1979-12-30

Description

This data set consists of time-averaged particle fluxes in interplanetary space and in the vicinity of Jupiter. It is on binary magnetic tape and was created on a PDP-11 computer. After time averaging, the data have been binned according to sector. Each logical record begins with header information dealing with the time interval for which measurements were collected and the averaging interval. This is followed by count rates from the 91 data channels in each of 8 sector positions plus a sector average. The species counted, the number of channels, and their energy ranges (in MeV for electrons and MeV/nucleon for other particles) are (1) electrons, 12 channels, 0.015 to > 8.5; (2) protons, 8 channels, 0.27 to > 240; (3) Z.GE.1, 8 channels, 0.03-4.01; (4) Z.GE.2, 2 channels, 0.98-4.22; (5) alphas, 11 channels, 0.075-64; (6) light nuclei, 3 channels, 0.60-21; (7) medium nuclei, 10 channels, 0.047-200; (8) heavy nuclei, 8 channels, 0.062 to > 125; (9) ions, 20 channels, 0.285 to 59; (10) miscellaneous singles, 8 channels; and (11) miscellaneous coincidence, 1 channel. The spacing of channels is generally logarithmic. An estimate of counting rate uncertainties which follows this is in turn followed by the number of samples which go into determining each count rate (in terms of the basic accumulation interval). The remainder of the data set consists of reduced data. Fluxes corresponding to the count rates mentioned above have been calculated by applying corrections for dead time, geometrical factors, and passband. Following this is an estimate of the flux uncertainties. The time resolution is usually 15 minutes or 1 hour.
