A layout showing the several physical parameters measured by one satellite in the THEMIS mission on January 29, 2008. From top to bottom, the panels show, respectively, the energy spectrum of energetic ions, the energy spectrum of thermal ions, the energy spectrum of energetic electrons, the energy spectrum of thermal electrons, the angular anisotropy of energetic ions, the electric field fluctuations at high frequencies, the magnetic field fluctuations at high frequencies, the three components of the ion velocity, and the three components of local magnetic field.
