darkhistory.physics.f_std

darkhistory.physics.f_std(mDM, rs, inj_particle=None, inj_type=None, struct=False, channel=None)

energy deposition fraction into channel c, f_c(z), as a function of dark matter mass and redshift.

Parameters:

mDMfloat

Dark matter mass

inj_particlestring

Injected particle, either set to ‘phot’ for photons, or ‘elec’ for electrons.

inj_typestring

Type of energy injection, either ‘swave’ or ‘decay

structbool

If True, include structure formation, if False assume no structure formation. Default is False. This option makes no difference for decays.
