bkn2pow: broken power law, 2 break energies
A three-segment broken power law (ie with two break energies).

|
E £ Ebreak,1 |
|
|
Ebreak,1 ≤ E ≤ Ebreak,2 |
|
|
|
Ebreak,2 ≤ E |
where :
|
par1= |
power law photon index for E < Ebreak,1 |
|
par2=Ebreak,1 |
first break point for the energy, keV |
|
par3= |
power law photon index for Ebreak,1 < E < Ebreak,2 |
|
par4=Ebreak,2 |
second break point for the energy, keV |
|
par5= |
power law photon index for E > Ebreak,2 |
|
Norm =K |
photons keV-1cm-2s-1 at 1 keV |
