        "Description": "This data set contains 17 differential fluxes of\nprotons (mainly), helium ions, Z.GE.6 ions, and electrons, plus one integral\nflux of protons and electrons, as averaged over polar cap passes of the\nSAMPEX spacecraft.  A polar cap pass covers the time poleward of geomagnetic\nlatitude 70 deg.  (Not all orbits have two polar cap passes.).  For any\ngiven species, the fluxes typically come from more than one of the sensors\n(LICA, HILT, MAST, PET).  Hence the inclusion of all instruments' data in\neach single record.  Differential fluxes are those for (mainly) protons\n(Z.GE.1 channels at 5-12 and 19-27 MeV/n), helium ions (0.50-6.6, 4-9, 8-15,\n9-38 MeV/n), Z.GE.6 ions (0.49-8.3, 8-42, 19.3-22.8, 22.8-31.0, 31.0-51.7,\n41-220, 51.7-76.2, 76.2-113, 113-156 MeV/n), and electrons (1.5-6.0 MeV\nfrom PET only). One LICA channel measured integral fluxes of ions .GT. 0.8 MeV/n\nplus electrons .GT. 0.6 MeV).  Data available for each polar cap pass are time\ntags of the begin and end points of the averaging interval, the fluxes,\nstatistical uncertainties in the fluxes, instrument-specific flags, and a\nflag indicating a north or south polar cap pass.  Data are organized in two\ndifferent ways.  Monthly ~500-KB ASCII files with records organized by instrument\nare available from the SAMPEX Data Center at Caltech and from nssdcftp at\nGSFC/SPDF, while monthly ~260 KB CDF-formatted files with records organized by\nspecies are available from the ftp area underlying CDAWeb.  The parameter level\ninformation given below in this descriptor corresponds to the CDAWeb organization\nof data.  Format information for the ASCII version is given in the Information\nURL of this descriptor.",
