NOTE: This model is now in the Xspec release and this page is superceded by the Xspec manualThe multiblackbody "Self-IrRdaiated Funnel" model is designed to model optically-thick outflow-dominated accretion. The basic idea is simple: you just assume a lot of matter, angular momentum and energy emerges in a limited volume. Momentum conservation leads to non-sphericity of the flow that has subsequently conical (funnel-like) shape. The model calculates temperature distribution at the funnel walls (taking into account irradiation by iterative process) and the outer photosphere. We also assume that inside the cone there is a deep pseudo-photosphere. Relativistic boosts are taken into account for high velocities. For a comprehensive description of the physical model, see: Abolmasov, P., Karpov, S. and Kotani, T. PASJ, 61, 2, 213.
par1 = tin, inner temperature (at the inner, inside-the-funnel photosphere).

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.
