VG2 URA PLS DERIVED SUMMARY ION FIT 48SEC V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: July 18, 2025 | Last Modified: 2025-07-17
This data set contains the total ion density obtained from Voyager 2 PLS data (voltage range 10-5950 eV/Q) at Uranus by fitting the measured spectra with isotropic Maxwellian distributions. It is a subset of the data set VG2-U-PLS-5-RDR-IONFIT-48SEC. Up to three isotropic proton components (warm, hot and intermediate) were used to match the observations. These were then summed to give total ion density. This determination does not include possible plasma outside the PLS energy range derived in the charging region from 1939-2158 on day 24. It is found that if a cold component exists it will increase the total ion density by at most a factor of two. uncertainties in plasma parameters are a factor of 2 in the charging region, less than 20% elsewhere. A complete description of this data set is given in McNutt et al. (1987) and Selesnick and McNutt (1987). Data format: first six columns are time tags (6I4), last column is total ion density in CM-3 (E11.3). Values of 1.E32 indicate that the parameter could not be obtained from the data using the standard analysis technique. Additional information about this dataset and the instrument which produced it can be found elsewhere in this catalog. An overview of the data in this data set can be found in McNutt et al. (1987) and Selesnick and McNutt (1987) and a complete instrument description can be found in Bridge (1977).
