512 Second Proton, Helium and Heavy Ion (Z>2) Rate Data


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

Time span: 1980-01-01 to 1981-12-31


This data set, supplied by the experimenter, consists of counting rates in many energy channels for protons (0.03 to 20 MeV), helium ions, and heavier ions. Fluxes may be readily obtained by use of the data set documentation. The data were written in multiple files on magnetic tape using IBM 360 binary representation. Logical record length is 400 bytes and block size is 6400 bytes. The data set has a time resolution of 512 s and contains quantities selected from only two of the instrument sensor systems: the electrostatic deflection analyzer (ULECA) and the wide angle proportional counter/solid state detector telescope (ULEWAT). Data from within the earth's magnetosphere are excluded, as are data affected by sunlight. Information included are: tape and experiment identifiers, times (UT), spacecraft clock, various housekeeping parameters, position in GSE Cartesian coordinates, spin period, indicators of the spin angle sectors that were averaged together (out of eight sectors), and 31 pairs of accumulated counts and accumulation time. The 31 count/time pairs correspond to 11 energy channels for protons from 0.03 to 20 MeV, 7 channels for helium ions from 0.015 to 20 MeV, and 3 channels for heavy ions (Z>2) from 0.13 to 43 MeV/nucleon, plus 10 monitor rates, which are single rates from individual detectors relevant to the other 21 rates that are coincidence rates. This data set includes only parameters that do not require very detailed knowledge of the instrument. The more detailed data, which require substantial involvement of the experimenters, may be obtained directly through the principal investigator.
