This experimenter-supplied data set contains solar proton data on reels of 35-mm microfilm and one reel of 16-mm microfilm. Data listed include reduced velocity step counts (energy spectra), the location number of the 22.5-deg sector where maximum counts were recorded, an indication of the azimuthal angular spread in the incoming flux of particles, derived plasma fluid parameters for each energy spectra, ephemeris information, and the thermal speed to convection speed ratio. Data are given separately for both protons and alpha particles. The time between each spectra is 3 min, with the time to acquire one spectra being 1 min. The plasma parameters were derived by fitting a series of convected Maxwellian distribution functions to the velocity step spectrum, considering three points at a time. The resulting distribution function was used to calculate the density, mean velocity, and temperature by the method of moments. Data are available with 95% coverage from May 27, 1967, to January 30, 1968.
