XSlaor2

class sherpa.astro.xspec.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 and RoutG parameters have been renamed to Rin_G and Rout_G respectively to match the XSPEC definition. The names RinG and RoutG 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.

get_center() [edit on github]
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.

regrid(*arrays) [edit on github]
reset() [edit on github]
set_center(*args, **kwargs) [edit on github]
startup() [edit on github]

Called before a model may be evaluated multiple times.
