Sherpa Models

The models available in Sherpa are listed below. The full list may be accessed within Sherpa using the list_models() command.

The following Sherpa models are designed for use with spectra or SEDs at optical wavelengths, which means that where relevant, position, line width, and other similar model parameters have units of Angstroms.

Sherpa includes the "additive" and "multiplicative" models of XSpec version 12.7. The XSpec model names have the prefix "xs", e.g. XSpec phabs model is called "xsphabs"; see "ahelp xs" for general information on the XSpec models in Sherpa.
