This dataset is NOT summed over polar angle but can in some cases be summed over energy.  Including: - The 3DF dataset contains FULL resolution three dimensional electron distribution. - The 3DX1 and 3DX2 datasets contains the variable resolution three dimensional electron distribution with no summing. - The 3DXE1 and 3DXE2 datasets contains the variable resolution three dimensional electron distribution which has been summed over pairs of ENERGY bins.  For the MAR/HAR modes the maximum extent of the data structure (including flyback information) will be 64 azimuths x 12 polar angles x 32 energy bins.  The exact energy and azimuth binning is determined from the specific mode (MAR/HAR).",
