PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION This dataset contains daily averages of Voyager 2 data.The columns are:1. decimal year2. day3. V2-Sun-Earth angle4. V2 heliolatitude5. Earth heliolatitude6. V2 heliolongitude7. Earth heliolongitude8. VR (km/s, RTN coordinate system)9. VT10. VN11. Den (cm-3, moment)12. Den (cm-3, fit) These are best values to use13. W (thermal speed, km/s, moment) T(ev)=0.0052*W*W14. W (thermal speed, km/s, fit) T(ev)=0.0052*W*W These are best values to use15. R (AU, distance from Sun)Sometimes either the low density or noise causesthe standard V2 analysis to fail. In these caseswe have looked carefully at the spectra, at spectrograms,averaged data, looked at lower energy resolution L-modedata, and done anything possible to determine reasonableplasma parameters. In some cases, when we use L mode data,we have had to fix the thermal speed of the plasma based onprevious and subsequent observed values. In all these caseswe assume the flow is purely radial. The daily averages labeled'augmented' have these values added; the other daily averages haveonly values from our standard analysis. The data formatsare identical.
