XSoptxagn
(name='optxagn')[source] [edit on github]¶ 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 renamedlogLoLedd
to match the XSPEC definition. The namelogLLEdd
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.
-
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.

guess
(dep, *args, **kwargs) [edit on github]¶ Set an initial guess for the parameter values.
Attempt to set the parameter values, and ranges, for the model to match the data values. This is intended as a rough guess, so it is expected that the model is only evaluated a small number of times, if at all.
