This Level-2 CDF dataset from all four SAMPEX experiments, HILT, LICA, MAST, and PET is accessible through NSSDC's CDAWEB. Each file covers one month of polarcap averaged fluxes of cosmic rays from 18 channels from all experiments, written in ASCII. There are 58 variables per record, and the file size is about 630 KB. With a period of 2 hr, there are about 26 polar averages/day for each channel. After a small list of ancillary data, the particle fluxes follow. (1) LICA provides fluxes of electrons and protons in the energy range of about >0.7 Mev, of (mainly) helium in the range 0.49-8.3 MeV/nucleon. (2) HILT provides fluxes of helium from two channels, 4-9 and 9-38, of Z > 5 from two channels, 8.2-42 and 41-220 MeV/n. (3) MAST provides fluxes protons (mainly) in 5-12 MeV range, of helium in 8-15, and of Z > 5 in 19.3-22.8, 22.8-31.0, 31.0-51.7, 51.7-76.2, 76.2-113, 113-156 MeV/n. (4) PET provides fluxes of electrons in the ranges 1.5-6, and 2.5-14 MeV, and of (mainly) protons in 19-27 MeV/n. All flux values are accompanied by their standard deviations and quality flags. The fluxes available in this file are from a subset of channels that have provided polarcap rates. This dataset is basically a CDF version of ASCO-00005, but many of the variables in in that collection are condensed into arrays of energy spectra in this CDF version, assembled by pick-and-choose across instrument boundaries; an example is the 8-element array of Z>3 fluxes that have contributions from all four instruments.
