XSslimbh

class sherpa.astro.xspec.XSslimbh(name='slimbh')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC slimbh model: Stationary slim accretion disk.

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.

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 contorl 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.

Notes

This model is only available when used with XSPEC 12.9.1 or later.
