XSdiskir

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

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC diskir model: Irradiated inner and outer disk.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

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

kT_disk

The temperature of the innermost part of the unilluminated disk, in keV.

Gamma

The asymptotic power-law photon index.

kT_e

The electron temperature (high-energy rollover) in keV.

LcovrLd

The ratio of the luminosity in the Compton tail to that of the unilluminated disk.

fin

The fraction of luminosity in the Compton tail which is thermalized in the inner disk. Generally fix at 0.1 as appropriate for an albedo of 0.3 and solid angle of 0.3.

rirr

The radius of the Compton illuminated disk in terms of the inner disk radius.

fout

The fraction of bolometric flux which is thermalized in the outer disk.

logrout

The log (base 10) of the outer disk radius in terms of the inner disk radius.

norm

The model normalization: it is the same definition as used for the XSdiskbb model.

calc(pars, xlo, *args, **kwargs) [edit on github]
get_center() [edit on github]
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.

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.
