The 3DXPA product contains only the 3DX azimuths that are most closely aligned parallel and anti-parallel with the onboard magnetic field direction.  It is up to the user to decide which azimuth is closest to the real field directions by examining the (ground produced) Pitch Angle data included in the file.  For the MAR/HAR modes the maximum extent of the data structure (including flyback information) will be 8 azimuths x 12 polar angles x 32 energy bins.  The exact energy and azimuth binning is determined from the specific mode (MAR/HAR) the Cluster C1 spacecraft in LAR mode only. The 3DXLAR product contains only the 3DX azimuths that are aligned parallel and anti-parallel with the onboard magnetic field direction.  For the LAR mode the extent of the data structure (including flyback information) will be 2 azimuths x 12 polar angles x 64 energy bins.",
