XSdiskline

class sherpa.astro.xspec.XSdiskline(name='diskline')[source] [edit on github]

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC diskline model: accretion disk line emission, relativistic.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

The RinM and RoutM parameters have been renamed Rin_M and Rout_M respectively to match the XSPEC definition. The names RinM and RoutM can still be used to access the parameters, but they will be removed in a future release.

LineE

The line energy in keV.

Betor10

The power law dependence of emissivity: see [1] for more details.

Rin_M

The inner radius, in units of GM^2/c.

Rout_M

The outer radius, in units of GM^2/c.

Incl

The inclination, in degrees.

norm

The model normalization in photon/cm^2/s.

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.
