The reflectivity algorithm for laterally varying earth models              is too slow to be practical for modeling refraction data when the               vertical direction is the imbedding direction.  However when the                horizontal direction is made the direction of imbedding the cost                of computation increase (at most) linearly with source-receiver                 offset.                                                                                                                                                              In general the horizontal propagator has a continuous                      spectrum and a point spectrum.  The point spectrum is large and                 troublesome to locate at body-wave frequencies but the location of              the continuous spectrum is always known.  By adding a low-velocity              lower half space to the model the continuous spectrum is enlarged               at the expense of the point spectrum.  We propose to treat lateral              heterogeneity by coupling together the continuous spectra of                    adjacent vertical slices.
