Interface to produce listings/plots with filtering

This page provides the ability to list/plot (or create a file of) any selection of the Voyager2 parameters listed below, only for hours when these and/or other parameters satisfy user-specified numeric ranges. Optional: click left boxes to select output parameters, and enter desired minimum and/or maximum value(s) in box(es) to the right of any desired "filtering" parameter(s).

Note: Voyager magnetometer data past 1989 must be used very carefully due to the very low magnetic field values being measured as compared to the pre-launch magnetometer accuracy requirements. Please click here for details.
