Parameter Plots & Comparison with Other Publications
On this page we provide text files and plots of the Ion Parameters that were derived at CU-LASP with the Viper code, text files and plots of the Electron Parameters that were derived by Sittler & Strobel (1987), plus electron densities derived from plasma wave data obtained by the PWS instrument and analyzed by Warwick et al. (1979) and Birmingham et al. (1981). Re-analysis of the Voyager PLS ion data was performed by Logan Dougherty & Kaleb Bodisch – see Papers 1,2,3. The scanning and digitizing of previously published data was done by Grace Marshall.
