Data Set Overview
      =================
      This data set contains combined and correlated results from the
      Johnstone Particle Analyser (JPA) and magnetometer experiments
      flown aboard the Giotto spacecraft during its extended mision to
      fly by comet P/Grigg-Skjellerup.
 
 
      Parameters
      ==========
 
      There are two data files in this set:
 
        jpamg_sc     provides results in the spacecraft frame of reference.
                     This file lists time, proton density velocity and
                     temperature, and magnetic field values, with additional
                     related parameters.
 
        jpamgcse     provides results in the comet-Sun-ecliptic frame.
                     This file lists time and position, proton velocity,
                     electric and magnetic field vectors, and drift velocity
                     (ExB).
 
      Processing
      ==========
      The files were received as ASCII table from the project team.  SBN
      personal performed cosmetic reformatting (removing extra blanks) and
      prepared the PDS documentation.  No changes were made to the data
      values after receipt.
 
      Media/Format
      ============
      These data are included in the GEM CDROM disk prepared by the PDS
      Small Bodies Node.

Confidence Level Overview
      =========================
      Note that while this data has undergone the standard internal PDS
      review, no external review has been held.
