Fig. 9From: Visualization tool for three-dimensional plasma velocity distributions (ISEE_3D) as a plug-in for SPEDASProton and magnetic field observations by the MMS1 spacecraft on October 16, 2015, near the dayside magnetopause. (Top) Energy–time spectrogram of the omnidirectional ion flux from the HPCA instrument, (middle) three components in GSM coordinates and the magnitude of the magnetic field from the FGM instrument, and (bottom) three components of the proton velocity in GSM coordinates from the HPCA instrument. The vertical dashed line indicates the time interval for which the 3D proton velocity distribution is shown in Fig. 10 Back to article page
