SPEC: Energy Spectrum for Elements

Overview

SPEC outputs the differential and/or integral energy spectra for a single cosmic ray element.

Inputs

SPEC options are:

• Name(s) of output file(s)
• Number of data points in output file(s)
• The atomic number of the ion whose spectra you want
• The year
• Whether to include geomagnetic cutoff and trapped protons
• The interplanetary weather index
• The thickness of material shielding.

Outputs

The output files of SPEC are in two columns: the first column is differential flux in particles/(m²-ster-sec)/(MeV/u) or integral flux in particles/(m²-ster-sec); the second column is energy in MeV/u.
