Synopsis

E-folded power law reflected from an ionized relativistic disk. XSpec model.

Description

Exponentially cutoff power law spectrum reflected from an ionized relativistic accretion disk. In this model, spectrum of 'xspexriv' is convolved with a relativistic disk line profile ('xsdiskline'). See Magdziarz and Zdziarski 1995 MNRAS, 273, 837 for details of Compton reflection and Fabian et al. 1989, MNRAS, 238, 729 for details of the disk line profile.

xsrefsch Parameters

Number Name Description
1 PhoIndex power law photon index, N_E prop. to E^(-PhoIndex)
2 foldE the cutoff energy in keV (if foldE=0 there is no cutoff)
3 relRefl reflection scaling factor (1 for isotropic source above disk)
4 redshift redshift, z
5 abund abundance of elements heavier than He relative to the solar abundances
6 FeAbund iron abundance relative to the above
7 Incl inclination angle (degrees)
8 Tdisk disk temperature in K
9 xi disk ionization parameter, xi = 4 pi F_ion/n, where F_ion is the 5 eV - 20 keV irradiating flux and n is the density of the reflector; see Done et al., 1992, ApJ, 395, 275
10 Betor10 power law index for reflection emissivity; emissivity is proportional to r^Betor10
11 Rin inner disk radius (GM/c^2)
12 Rout outer disk radius (GM/c^2)
13 accuracy internal model accurancy - points of spectrum per energy decade
14 norm photon flux at 1 keV of the cutoff broken power law only (no reflection) in the observed frame
