Line profiles from the Shakura–Sunyaev accretion disk. The top row shows the profiles associated with a coronal height of 2.5 r_g, the middle row shows the same for coronal heights of 5 and 10 r_g, and the bottom row is for 20 r_g. The columns correspond to different inclination angles of observation i. The blue line corresponds to the flat disk, the orange line to the disk with ﹩\dot{M}/{\dot{M}}_{\,\rm{Edd}\,}=0.3﹩, the green line to ﹩\dot{M}/{\dot{M}}_{\,\rm{Edd}\,}=0.7﹩, and the pink line to ﹩\dot{M}/{\dot{M}}_{\,\rm{Edd}\,}=1.1﹩.
