Description
Both spectral energy distribution (SED) of the continuum and the spectral lines offer a way to measure and model parameters of the inner and outer region of the black hole accretion disc. We introduce a perturbative term located in the orbital plane of the accretion disc and parametrize the spectral changes to reveal the decrease of the emissivity of the expected signal. We assume three different scenarios (i) an inner optically hot flow component; (ii) a secondary black hole component; or (iii) a combination of both. We address the qualitative differences of the spectral features with respect to the standard disc-line scenario and discuss the conditions and methods used to constrain the parameters of the system.
