  "x_description": "This dataset contains preliminary spin resolution measurements of the electron velocity distribution function at the satellite in three dimensions from the PEACE experiment on the Cluster C4 spacecraft. These data have been converted into Cluster Exchange Format from the orignal 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.  Version 01 of this dataset is the initial translation prepared for the launch of the CAA during the second half of 2005.",
