Normalized MAVEN penetrating proton data (2014-2018)

These data were generated using SWIA & NGIMS plasma and particle data collected on the MAVEN spacecraft.  These data products were used to obtain the results found in a paper submitted to JGR:  Planets, "An Analysis of Precipitating Solar Wind Hydrogen as Observed by the MAVEN Spacecraft".  The data columns are as follows:

Time [s]:  This corresponds to the epoch time (ie number of seconds since January 1, 1970) at which each penetrating proton measurement was taken.

Altitude [km]:  MAVEN's altitude in kilometers at the time of the penetrating proton measurement.

Column Density [cm^-2]:  The column density at the point of the penetrating proton measurements (details of calculation can be found in paper) in inverse squared centimeters.

Normalized Height:  This is the unitless, normalized height of each penetrating proton spectrum measured by SWIA.  Details of the normalization procedure can be found in the paper listed above.  

Normalized Width:  This is the full width at half max divided by the peak energy for each modeled penetrating proton profile.  This quantity is unitless.

SZA [degrees]:  This is the solar zenith angle in degrees at which the penetrating proton measurement was taken.

Energy [eV]:  This is the peak energy of each modeled penetrating proton profile in electronvolts.
