Fig. 10.


Polarisation signal as a function of the energy for the case of a slab corona with τ = 1 and kTe = 100 keV decomposed in scattering orders as indicated inside the figure. The seed photons produced by the disc are unpolarised and the system is observed at 75° inclination. Upper panel: polarisation degree. Lower panel: absolute value of the corresponding polarisation angle.
