`spacepy.empiricals.``getSolarProtonSpectra`(norm=32000000.0, gamma=-0.96, E0=15.0, Emin=0.1, Emax=600, nsteps=100)

  Returns a SpaceData with energy and fluence spectra of solar particle events

  The formulation follows that of: Ellison and Ramaty ApJ 298: 400-408, 1985 dJ/dE = K^{-gamma}exp(-E/E0)

  and the defualt values are the 10/16/2003 SEP event of: Mewaldt, R. A., et al. (2005), J. Geophys. Res., 110, A09S18, doi:10.1029/2005JA011038.

  Returns: | data : dm.SpaceData SpaceData with the energy and fluence values
  Other Parameters:
  | norm : float Normilization factor for the intensity of the SEP event gamma : float Power law index E0 : float Expoential scaling factor Emin : float Minimum energy for fit Emax : float Maximum energy for fit nsteps : int The number of log spaced energy steps to return
