kerrd: optically thick accretion disk around a Kerr black hole

Optically thick extreme-Kerr disk model based on the same tranfer-function used in the laor Kerr disk-line model. Local emission is simply assumed to be the diluted blackbody. See Laor (1991) for an explanation of the transfer function. See Ebisawa et al. (2003) for examples of using this model.

par1 | distance (kpc) |

par2 | spectral hardening factor, Tcol/Teff. Should be greater than 1.0, and considered to be 1.5-1.9 for accretion disks around a stellar-mass black hole. See, e.g., Shimura & Takahara (1995) 445, 780 |

par3 | mass of the central object (solar unit) |

par4 | mass accretion rate ( g/s) |

par5 | disk inclination angle (deg; 0 for face-on) |

par6 | inner radius (units of ). 1.235 is the last stable orbit. |

par7 | outer radius (units of ) |

K | normalization factor. should be fixed to 1. |
