  "x_description": "This dataset contains preliminary spin resolution measurements of the emitted current from the ASPOC experiment on the Double Star TC1 spacecraft. ASPOC provides one parameter, namely the emitted ion current I_ion, for both the PPDB and SPDB. The measured quantity is the net current flowing from the emitter into space. A current in the described direction is considered positive. The units are microamperes. The data are sampled every 40 ms. The raw data contain 0.5 s averages, from which the PPDB and SPDB data are obtained. These data have been converted into Cluster Exchange Format from the orignal Double Star Science Data System Common Data Format (CDF) Prime Parameter files that were made available through the Double Star 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 CAA during 2015.",
