XSlaor2
(name='laor2')[source] [edit on github]¶ Bases:
sherpa.astro.xspec.XSAdditiveModel
The XSPEC laor2 model: accretion disk with broken-power law emissivity profile, black hole emission line.
The model is described at [1].
Note
Deprecated in Sherpa 4.10.0
The
RinG
andRoutG
parameters have been renamed toRin_G
andRout_G
respectively to match the XSPEC definition. The namesRinG
andRoutG
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.
-
Index
¶ The power law dependence of emissivity (scales as R^-Index).
-
Rin_G
¶ The inner radius, in units of GM/c^2.
-
Rout_G
¶ The outer radius, in units of GM/c^2.
-
Incl
¶ The disk inclination angle, in degrees. A face-on disk has Incl=0.
-
Rbreak
¶ The radius at which the emissivity power-law index changes.
-
Index1
¶ The emissivity power-law index for r>Rbreak.
-
norm
¶ The flux in the line, in units of photon/cm^2/s.

guess
(dep, *args, **kwargs)[source] [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.
