Description
SWIA onboard spectra files with time-ordered angle-averaged ion energy spectra in units of differential energy flux, as computed onboard from Coarse ion distributions, as well as a header with ancillary information needed to interpret the spectra. Description of the SWIA instrument can be found on the SWIA home page https://lasp.colorado.edu/maven/science/instrument-package/swia/ and in the SWIA instrument publication https://doi.org/10.1007/s11214-013-0029-z.
