drn_interface module

Class to simulate primary and secondary antiproton fluxes at the local interstellar region using DarkRayNet.

class pbarlike.drn_interface.DRNet(propagation_config, propagation_parameters, prevent_extrapolation, verbose=False)

Bases: object

Contains methods that transform the user inputs (propagation parameters, DM mass, branching fractions) as required by DMNet (simulates primary antiproton flux) and sNet (simulates secondary antiproton flux) and methods that postprocess network ouputs to user usable forms.

Parameters:

  • propagation_config (object) – Object of class Propagation

  • propagation_parameters (list or array) – propagation parameters

  • prevent_extrapolation (bool) – Whether network should be allowed to predict in untrained parameter regions; default - True

DM_LIS_sim()

Simulates primary and secondary antiproton fluxes at the local interstellar region using DMNet and sNet respectively.

preprocessing_DMparams(DM_mass, br_fr, sigma_v)

Preprocesses DM masses, annihliation cross-sections and branching fractions as required by the DMNet.

preprocessing_prop_params(propagation_parameters)

Checks validity of given propagation parameters and defaults to multinest sample if conditions are not met.

Gives a set of propagation parameters obtained from a fit of proton and helium fluxes to AMS-02 and Voyager data, for the DIFF.BRK model.
