This interface provides access to proton plasma parameters computed at MIT both by moments and nonlinear fits techniques, for both solar wind and magnetosheath phases of the IMP 8 orbit. Each record includes an orbit phase indicator determined at MIT. This interface allows users to limit searches using this indicator (e.g., for solar-wind-only searches) The underlying annual ASCII files are ftp-accessible from Detailed documentation is available from the readme file in that directory.
