Abstrakt (anglicky)
   First-order ray tracing (FORT) and dynamic ray tracing (FODRT) for P waves provide approximate, but simple and quite accurate way of computing traveltimes and geometrical spreading of seismic waves propagating in inhomogeneous, weakly anisotropic media and even in media of moderate anisotropy. FORT is a technique based on perturbation theory, in which deviations of anisotropy from isotropy are considered to be small quantities, used further in the perturbation procedure, The basic idea of FORT is to replace the exact eigenvalue of the Christoffel matrix, which controls P-wave ray tracing and dynamic ray tracing, by its first-order counterpart.
