Extra XSPEC local models. These additional models are not included in the release.
For more information on local models, see the Xspec webpage.
To use any of these models in XSPEC, place the model contents in a directory, start up XSPEC, and use the initpackage command to build the model. This need only be done once. Then use the lmod command to load in the model. This must be done once in each XSPEC run.
