Measurements of electrons and positive ions are acquired simultaneously. Measurements from the Hot Plasma analyzer are available at this Web site in a graphical survey format. This format is designed to provide convenient access to the observations. Each survey plot is a five-day record of the electron and ion intensities and several parameters derived from those intensities. The measurements are given in a sequence of five panels.
Positive flow is towards the sun.
The intensities of positive ions as a function of particle energy. The intensities of electrons as a function of particle energy. The particle intensities given in panels 4 and 5 are five-minute accumulations from the ion and electron sensors that view the ecliptic plane. This plane is perpendicular to the spin axis of the spacecraft, and the intensities are summed over eight equally spaced spin sectors. The particle intensities are color coded according to the logarithmic color bar on the right-hand side of the figure which has separate scales for ions and electrons.
