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. |
