        "Description": "\n   Hourly averages and peaks of calibrated electric field spectrum analyzer data from Voyager 1 PWS instrument\n    \n   The plasma parameters are obtained by finding the best fit of a convected   \n   isotropic Maxwellian distribution to the data. One sigma errors             \n   are typically less than 0.5% in the speed and VR, less than 5% for the      \n   density and thermal speed, and vary greatly for VT and VN.                  \n   Sampling times range from 12 to 192 sec., with sampling generally more      \n   frequent early in the mission.\n                     \n   The velocity components are given in the RTN coordinate system,             \n   where R is radially outward, T is in a plane parallel to the solar          \n   equatorial plane and positive in the direction of solar rotation,           \n   and N completes a right-handed system.                                      \n",
