class SourceGenericComposition : public SourceFeature

Add multiple cosmic rays with energies described by an expression string.

This is particularly useful if an arbitrary combination of nuclei types with specific energy spectra. The strings parsed may contain ‘A’ (atomic mass), ‘Z’ (atomic number). The following units are recognized as part of the strings: GeV, TeV, PeV, EeV. The variable for energy is ‘E’, with limits ‘Emin’, ‘Emax’. This property only works if muparser is available. For details about the library see: https://beltoforion.de/en/muparser/

SourceGenericComposition(double Emin, double Emax, std::string expression, size_t bins = 1024)

Constructor

Parameters:

  • Emin – minimum energy [in Joules]

  • Emax – maximum energy [in Joules]

  • expression – string containing the expression to generate the composition

  • bins – number of energy bins

void add(int id, double abundance)

Add an individual particle id.

Parameters:

  • id – id of the particle following the PDG numbering scheme

  • abundance – relative abundance of individual particle species

void add(int A, int Z, double abundance)

Add an individual particle id.

Parameters:

  • A – atomic mass of the cosmic-ray nucleus

  • Z – atomic number of the cosmic-ray nucleus

  • abundance – relative abundance of individual particle species
