    Abstract:
    We develop a method of calculating the X-ray signal from a ‚spot‘
    corotating with an accretion disk around a black hole and the emission
    line from the X-ray-illuminated disk. The disk self-eclipse is
    considered, and all effects of general relativity on the motion of
    photons are included with no approximation. The eclipse strongly affects
    the shape of the X-ray light curve of the spot and the K fluorescent
    line irradiated by the disk. The FWHM and strength of the line profile
    are reduced significantly if the eclipsed region of the orbit is very
    deep. For a given radius of a ring in the disk, this occurs when the
    eclipsed region of the orbit is deeper than pi/2. The centroid of a line
    profile is also subject to the eclipse effect.
