kerrdisk: accretion disk line emission with BH spin as free parameter
Model for an accretion disk broad emission line with the black hole spin allowed to be a free parameter. A detailed description can be found in Brenneman & Reynolds (2006).
This model is quite slow so is best used after models such as laor or diskline have been employed to get an estimate of the best-fit parameters.
