        "Description": "Reference: HYDRA is a 3-Dimensional Electron and Ion Hot Plasma Instrumentfor the Polar Spacecraft of the GGS Mission, J. Scudder et al., Space Sci. Rev., 71,459-495, Feb. 1995. http://www-st.physics.uiowa.edu This data set contains the differential electron and proton omnidirectional fluxes per unit solid angle vs energy, at 13.8-second resolution.  Multiply the given value by 4 pi to obtain the total omnidirectional differential energy flux.There are 29 energy channels from 12.5 ev to 18.3 keV.HYDRA is composed of two boxes, each housing 6 detectors.A separate stepping power supply is used for each box.The values of these steps are designed to be interlaced.Therefore, the energies designated in this file are interpolated between the values of the two power supplies.Stepping modes may also vary the number and range of steps during the mission.  To accommodate these changes an interpolation is done from the steps for a particular mode to the common energy values listed in ENERGY_ELE and ENERGY_ION.",
