Paolo Coppi's hybrid (thermal/non-thermal) hot plasma emission model
NOTE: This model is now in the Xspec release and this page is superceded by the Xspec manualThese three models are based on Paolo Coppi's hybrid thermal/non-thermal hot plasma emission model for X-ray binaries. The underlying physics and a detailed description of the code are included in this draft paper. Do not use these models without reading and understanding this paper. The original website for these models is http://www.astro.yale.edu/coppi/eqpair. The parameters for eqpair are
par1 = l_h/l_s, ratio of the hard to soft compactnesses
Simplified models eqtherm and compth are provided for cases where non-thermal processes are not important and photon-photon pair production can be ignored. These should only be used if l_bb <~ 10.
The source code and required data files are included in this gzipped tar file. You will need to edit the file xseqpair.f to ensure that DATADIR points to the correct directory.

The HEASARC welcomes your participation in a brief survey to capture how users access and utilize HEASARC data, software, and services. The outcome(s) of this survey will be used to guide, prioritize, and plan our activities and development in the coming years. It contains 20 questions, generally takes just a few minutes to complete, and your answers will remain totally anonymous. The survey is open until Dec 18, 2023. We thank you in advance for your valuable feedback.
