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 (2006ApJ...652.1028B).
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.
par1 = rest frame line energy (keV)
par2 = emissivity index for the inner disk
par3 = emissivity index for the outer disk
par4 = break radius separating the inner and outer portions of the disk (gravitational radii)
par5 = dimensionless black hole spin
par6 = disk inclination angle to the line of sight (degrees)
par7 = inner radius of the disk in units of the radius of marginal stability
par8 = outer radius of the disk in units of the radius of marginal stability
par9 = redshift z
K = flux in line (photons/cm2/s)
