******************************************************************************** PVONMS ******************************************************************************** The software is available at the NASA/Goddard Space Flight Center. If interested contact PPI node or Dr. Kasprzak at Goddard. All data were processed at NASA/Goddard Space Flight Center using custom programmed software. The software is available. The data represent a reduction to physical units (density, flux) and were processed from an intermediate engineering unit file (current, count/sec etc.). Unit and 1/8 unit amu sweeps are not contained in the processed data sets but are available from the engineering unit data set. The engineering unit data is converted to ambient values using spacecraft velocity and attitude, the theoretical expected system response, and the corresponding calibration factors. Superthermal ion data for species other than O{+} is available in engineering unit form.
