    The XSPEC slimbh model: Stationary slim accretion disk.

xsslimbh
The xsslimbh model is an additive model component.

The model is described at [1] . The set_xsxset and get_xsxset

functions are used to set and query the XSPEC XSET "SLIMBB_DEBUG", "SLIMBB_DIR", and "SLIMBB_TABLE" parameters.

>>> create_model_component("xsslimbh", "mdl")
>>> print(mdl)

Create a component of the xsslimbh model and display its default parameters. The output is:

ATTRIBUTES

The attributes for this object are:

Attribute
Definition
M
The mass of the black hole, in M_sol.
a
The black hole spin parameter.
lumin
The total disk luminosity in Eddington units.
alpha
alpha-viscosity
inc
The inclination, in degrees.
D
The distance to the source, in kpc.
f_hard
The hardening factor. A negative value means to use TLUSTY spectra.
lflag
A flag to control the effect of limb-darkening. If greater than zero then the disk emission is limb-darkened, otherwise it is assumed to be isotropic.
vflag
A flag to control the surface profile. If greater than zero, raytracing is done from the actual photosphere, otherwise the spectrum is raytraced from the equatorial plane ignoring the height profile of the disk.
norm
The normalization of the model: see [1] for an explanation of the units.
