par2 a black hole spin parameter (dimensionless; 0<a<0.999)
par3 L luminosity (total disk luminosity in Eddington units)
par4 alpha alpha-viscosity
par5 i inclination (in degrees; 0<=i<=85)
par6 D distance to the source (in kpc)
par7 f hardening factor; negative value means to use TLUSTY spectra
par8 l_flag lflag, a flag to switch on/off the effect of limb-darkening (not allowed to be free). If positive, disk emission is limb-darkened; if <=0, disk emission is assumed to be isotropic
par9 z_flag switch on/off surface profile; if positive, raytracing is done from the actual photosphere; if <=0, spectrum is raytraced from the equatorial plane ignoring the height profile of the disk
par10 K normalization (should be fixed to 1)

### Data
FITS table with spectral data: (slimbb-full.fits)[http://astro.cas.cz/bursa/projects/slimbb/slimbb-full.fits]
### Usage in XSPEC
The model requires a FITS table with pre-computed spectral data.
