FPI uses a trapezoidal triple integration scheme for its calculation of plasma moments. First, phase space density skymaps are integrated with respect to spacecraft azimuth (32 11.25o bins from 0-348.75o). Second, skymaps are integrated with respect to spacecraft elevation (16 11.25o 25o bins from 5.625 to 174.375o375o). Finally skymaps are integrated with respect to energy (32 bins from 10eV to 30keV). Energy and angle targets for a particular skymap are included as record varying entries in FPI distribution function CDFs. The reported energies are energy setpoints and do not include the effects of spacecraft potential which are obtained separately from EDP’s L2 FAST SCPOT CDF files.
