The XSPEC rgsxsrc convolution model: convolve an RGS spectrum for extended emission.
xsrgsxsrc The xsrgsxsrc model is a convolution model component.
The model is described at  .
>>> create_model_component("xsrgsxsrc", "mdl") >>> print(mdl)
Create a component of the xsrgsxsrc model and display its default parameters. The output is:
mdl Param Type Value Min Max Units ----- ---- ----- --- --- ----- mdl.order frozen -1 -3 -1
The attribute for this object is:
|order||The order, which must be -1 to -3 inclusive.|
Unlike XSPEC, the convolution model is applied directly to the model, or models, rather than using the multiplication symbol.
The set_xsxset function must be used to set the RGS_XSOURCE_FILE value to point to a file as described in  .

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.
