pexmon: neutral Compton reflection with self-consistent Fe and Ni lines.

This model from Nandra et al. (2007)
combines pexrav
with self-consistently generated Fe K, Fe K, Ni
K and the Fe K Compton shoulder. Line strengths are based on Monte Carlo calculations
by George & Fabian (1991)
which are parametrized for
by :

with inclination dependence for degrees :

and abundance dependence :

The Fe K and Ni K line fluxes are 11.3% and 5%
respectively of that for Fe K. The Fe K Compton shoulder is
approximated as a gaussian with E = 6.315 keV and
keV. The
inclination dependence is taken from Matt (2002)
such
that :

The model parameters are :

par1 |
, power-law photon index,
. |

par2 |
, cutoff energy in keV (if = 0 there is no cutoff). |

par3 |
scale, the scaling factor for reflection; <0 = no
direct component, 1 = isotropic source above the disk |

par4 |
, redshift |

par5 |
, abundance of elements heavier than He relative to Solar. |

par6 |
, iron abundance relative to Solar. |

par7 |
the inclination angle (degrees). |

norm |
normalization is the photon flux at 1 keV
(photons/keV/cm/s) of the cutoff power law only (without
reflection) and in the Earth frame. |
