The locally emitted disk spectrum is computed with a previously developed numerical model (Sincell and Krolik 1998) and then a new general relativistic ray-tracing code is used to determine the observed spectra as a function of inclination angle, theta_o. We find that Lyman discontinuities are undetectable for disks viewed at inclinations cos(theta_o) < 0.8, but a significant feature remains for disks seen face-on.2 pages, 1 figure, to appear in the proceedings for the Atelier ADJ-LAOG, "La relation accretion-ejection", Observatoire de GrenobleAstrophysicstext
