  "x_description": "This dataset contains summary 1 minute averaged measurements of the magnetic field vector from the FGM experiment on the Cluster reference spacecraft. These data have been converted into Cluster Exchange Format from the original Cluster Science Data System Common Data Format (CDF) Prime Parameter files that were made available through the Cluster Science Data System. The metadata has been updated from the CSDS/CDF standard to the CAA to aid compatibility with tools developed for the Cluster Active Archive.  The reference spacecraft may have changed during the course of the mission, and we recommend using the Data Mining datasets (C[1-4]_CP_FGM_DM) which are available for each spacecraft.  Version 01 of this dataset is the initial translation prepared for the launch of the CAA during the second half of 2005.",
