This bundle provides electron number density values derived from features observed
in plasma wave data obtained by the Cassini Radio and Plasma Wave Science (RPWS) instruments,
along with observed or derived characteristic frequencies, and useful positional parameters for
the spacecraft and related bodies. When present, frequency values of narrowband emissions at the
upper hybrid resonance were digitized and combined with measured or model magnetic field to derive
electron number density. At other times, features such as the upper cutoff in auroral hiss or electron
plasma oscillations were used to determine the plasma frequency and electron density.
