5-Minute Averaged Solar Wind Ion Data

Description

These data are contained on ASCII magnetic tape created on a VAX 11 computer. The records are of fixed length, with two records per physical block. The data consist of year, month, day and seconds of the day (UT); UT hours and minutes; spacecraft radial distance (Re), latitude (deg) and longitude (deg); spacecraft position in GSE coordinates; proton number density (1/cm**3) and bulk velocity (km/s); azimuthal flow angle (deg) and meridional flow angle (deg); alpha-proton flux ratio; and average proton temperature (deg K). The UT hours and minutes "are sometimes wrong near the end of an hour and should be ignored."
