XSkerrdisk

class sherpa.astro.xspec.XSkerrdisk(name='kerrdisk')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC kerrdisk model: accretion disk line emission with BH spin as free parameter.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

The r_brg, Rinms, and Routms parameters have been renamed to r_br_g, Rin_ms, and Rout_ms respectively to match the XSPEC definition. The names r_brg, Rinms, and Routms can still be used to access the parameters, but they will be removed in a future release.

lineE

The rest-frame line energy, in keV.

Index1

The emissivity index for the inner disk.

Index2

The emissivity index for the outer disk.

r_br_g

The break radius separating the inner and outer portions of the disk, in gravitational radii.

a

The dimensionless black hole spin.

Incl

The disk inclination angle, in degrees. A face-on disk has Incl=0.

Rin_ms

The inner radius of the disk, in units of the radius of marginal stability.

Rout_ms

The outer radius of the disk, in units of the radius of marginal stability.

z

The redshift of the source.

norm

The flux in the line, in units of photon/cm^2/s.
