5. Overview of the data (abstract):
We describe two families of Interactive Data Language (IDL) codes to calculate and display the dispersion relation for low frequency waves in Jupiter's polar cap.  One set of codes solves the cold plasma dispersion relation, while the other set solves the fully kinetic dispersion relation.
