Context: models

Synopsis

E-folded broken power law reflected from neutral matter. XSpec model.

Description

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.

xsbexrav Parameters

Number Name Description
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
9 redshift redshift, z
10 norm photon flux at 1 keV of the cutoff broken power law only (no reflection) in the observed frame.
