The XSPEC diskir model: Irradiated inner and outer disk.
xsdiskir The xsdiskir model is an additive model component.
The model is described at  .
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.

The attributes for this object are:
The temperature of the innermost part of the unilluminated disk, in keV.
The asymptotic power-law photon index.
The electron temperature (high-energy rollover) in keV.
The ratio of the luminosity in the Compton tail to that of the unilluminated disk.
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.
The radius of the Compton illuminated disk in terms of the inner disk radius.
The fraction of bolometric flux which is thermalized in the outer disk.
The log (base 10) of the outer disk radius in terms of the inner disk radius.
The model normalization: it is the same definition as used for the XSdiskbb model.

CIAO 4.12 comes with support for version 12.10.1n of the XSPEC models. This can be checked with the following:
% python -c 'from sherpa.astro import xspec; print(xspec.get_xsversion())' 12.10.1n
