We investigate the dependence of the viewing angle in supercritical accretion flows and discuss the observational implications of galactic black‐hole candidates and ultraluminous X‐ray sources. We find that if an object has a high inclination and high accretion rate, such a system suffers from self‐occultation and the spectrum will be extremely soft even if we take into account the effect of general relativity (light bending, Doppler boosting). We therefore cannot discriminate these differences… CONTINUE READING
