Jet contributions to the broad-band spectrum of Cyg X-1 in the hard state

Understand

We apply the jet model developed in the preceding paper of Zdziarski et al.

• to the hard-state emission spectra of Cyg X-1.
• We augment the model for the analytical treatment of the particle evolution beyond the energy dissipation region, and allow for various forms of the acceleration rate.
• We calculate the resulting electron and emission spectra as functions of the jet height, along with the emission spectra integrated over the outflow.
