Spectral energy distribution (SED, E²dN/dE, with N and E being the number and energy of the photons, respectively) for a simulated black hole in the soft state with a spin parameter a = 0.998, along with its polarization degree (PD, middle panel) and polarization angle (PA, bottom panel) for the total signal. The blue line shows the results for a geometrically thin optically thick, highly ionized (100% reflectivity) accretion disk seen at an inclination of 33﹩\mathop{.}\limits^{\unicode{x000b0}}﹩6. The red dotted curve shows the results when the reflection is switched off in the simulations. Neither model has a corona.
