E-folded broken power law reflected from neutral matter. XSpec model.
Broken power law spectrum multiplied by exponential high-energy cutoff Exp[-E/foldE] , and reflected from neutral material. See Magdziarz and Zdziarski 1995, MNRAS, 273, 837 for details. The output spectrum is the sum of an e-folded broken power law and the reflection component.
The reflection component alone can be obtained for relRefl < 0. Then the actual reflection normalization is |relRefl|. Note that you need to change then the limits of relRefl excluding zero (as then the direct component appears). If foldE = 0, there is no cutoff in the power law.
The metal and iron abundance are variable with respect to those set by a command set_xsabund. The opacities are of Balucinska and McCammon (1992 and 1994, private communication). As expected in AGNs, H and He are assumed to be fully ionized.
This is an additive model component.
|1||gamma1||first power law photon index|
|2||breakE||break energy (keV)|
|3||gamma2||second power law photon index|
|4||folde||the e-folding energy in keV (if foldE=0, there is no cutoff)|
|5||rel_refl||reflection scaling factor (1 for isotropic source above disk)|
|6||cosincl||cosine of inclination angle|
|7||abund||abundance of elements heavier than He relative to the solar abundances|
|8||fe_abund||iron abundance relative to the above|
|10||norm||photon flux at 1 keV of the cutoff broken power law only (no reflection) in the observed frame.|
