KERRBB: An XSPEC Subroutine for Computing the Blackbody Spectrum of a Thin Accretion Disk around a Kerr Black Hole
KERRBB is a multi-temperature blackbody model for a thin, steady state,
general relativistic accretion disk around a Kerr black hole. The self-irradiation
of the disk is considered, and the torque at the inner boundary of the disk is
allowed to be nonzero. The effect of Compton scattering in the disk atmosphere is
included. This model is intended as an extension to GRAD, which assumes that
the black hole is nonrotating.
