BrokenPowerLawElectronDistribution#
- class sunkit_spex.emission.BrokenPowerLawElectronDistribution(*, p, q, eelow, eebrk, eehigh, norm=True)[source]#
Bases:
object
A broken or double power law electron flux distribution and integral.
This class is intended to be use with
sunpy.emission.bremsstrahlung_thin_target
andbremsstrahlung_thick_target
.- Parameters:
p (
float
) – Power law index below the break energyebrk
q (
float
) – Power law index below the break energyebrk
eelow (
float
) – Low energy cutoffeebrk (
float
) – Break energyeehigh (
float
) – High energy cutoffnorm (
bool
(optional)) – True (default) distribution function is normalized so that the integral fromeelow
toeehigh
is 1.
