Triple Power Law
Introduction
The triple broken power law can be used to model the photon spectrum when there are two breaks in the non-thermal portion of the spectrum
Parameters
3pow - Triple broken power-law function with/without discontinuities in the derivatives
- a[0] - normalization at epivot, photon flux of first power-law at epivot
- a[1] - negative power law index below break energy one
- a[2] - break energy one (keV)
- a[3] - negative power law index above break energy two, below break energy two
- a[4] - break energy two (keV)
- a[5] - negative power law index above break energy two
