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 xspecabundan. 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.
xsbexrav Parameters
| 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 | relRefl | 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 | FeAbund | 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. |
