XSoptxagn

class sherpa.astro.xspec.XSoptxagn(name='optxagn')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC optxagn model: Colour temperature corrected disc and energetically coupled Comptonisation model for AGN.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

The logLLEdd parameter has been renamed logLoLedd to match the XSPEC definition. The name logLLEdd can still be used to access the parameter, but this name will be removed in a future release.

mass

The black hole mass in solar masses.

dist

The comoving (proper) distance in Mpc.

logLoLEdd

The Eddington ratio.

astar

The dimensionless black hole spin.

rcor

The coronal radius in Rg=GM/c^2. See [1] for more details.

logrout

The log of the outer radius of the disk in units of Rg. See [1] for more details.

kT_e

The electron temperature for the soft Comptonisation component (soft excess), in keV.

tau

The optical depth of the soft Comptonisation component. If this parameter is negative then only the soft Compton component is used.

Gamma

The spectral index of the hard Comptonisation component (‘power law’) which has temperature fixed to 100 keV.

fpl

The fraction of the power below rcor which is emitted in the hard comptonisation component. If this parameter is negative then only the hard Compton component is used.

fcol

The colour temperature correction to apply to the disc blackbody emission for radii below rcor with effective temperature > tscat.

tscat

The effective temperature limit, in K, used in the colour temperature correction.

Redshift

The redshift.

norm

The normalization of the model. It must be frozen.
