The XSPEC cpflux convolution model: calculate photon flux
xscpflux The xscpflux model is a convolution model component.
The model is described at  .
>>> create_model_component("xscpflux", "mdl") >>> print(mdl)
Create a component of the xscpflux model and display its default parameters. The output is:
mdl Param Type Value Min Max Units ----- ---- ----- --- --- ----- mdl.Emin frozen 0.5 0 1e+06 keV mdl.Emax frozen 10 0 1e+06 keV mdl.Flux thawed 1 0 1e+10
The attributes for this object are:
|Emin||Minimum energy over which the photon flux is calculated.|
|Emax||Maximum energy over which the photon flux is calculated.|
|Flux||photon flux in photon/cm^2/s|
Unlike XSPEC, the convolution model is applied directly to the model, or models, rather than using the multiplication symbol.
See  for the meaning and restrictions, in particular the necessity of freezing the amplitude, or normalization, of the emission component (or components) at 1.

Changes in CIAO
Added in CIAO 4.13
CIAO 4.15 comes with support for version 12.12.1c of the XSPEC models. This can be checked with the following:
% python -c 'from sherpa.astro import xspec; print(xspec.get_xsversion())' 12.12.1c
See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
