Exponentially cutoff power law reflected from neutral matter.
XSpec model.
 
Exponentially cutoff power law spectrum reflected from neutral
material (Magdziarz and Zdziarski 1995, MNRAS, 273, 837). The output
spectrum is the sum of an e-folded 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 then need to change the limits of relRefl to exclude 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 defined by the xspecabundan command. The opacities are from
Balucinska and McCammon (ApJ 400, 699 and 1994, private
communication). H and He are assumed to be fully ionized. 
 xspexrav Parameters
 
  | 1 | PhoIndx | power law
  photon index, N_E prop. to E^(-PhoIndx) |   
  | 2 | foldE | the e-folding
  energy in keV (if foldE=0, there is no cutoff; change the lower
  limit for that) |   
  | 3 | relRefl | reflection
  scaling factor; if < 0, there is no direct component; relRefl=1
  for isotropic source above disk |   
  | 4 | Redshift | redshift,
  z |   
  | 5 | abund | abundance of
  elements heavier than He relative to that defined by
  xspecabundan |   
  | 6 | FeAbund | iron
  abundance relative to that defined by xspecabundan |   
  | 7 | cosIncl | cosine of
  inclination angle |   
  | 8 | norm | photon flux at 1
  keV (photons/keV/cm^2/s) of the power law only in the observed
  frame |
