Synthetic seismograms for the case of the receiver within the reflectivity zone

Synthetic seismograms are shown and discussed for the case of the receiver within the medium. Most of the discussion is on the reflectivity method with the receiver within the reflectivity zone, but results using the ray method are shown for comparison. Such synthetic seismograms can be used to interpret data from Oblique Seismic Experiments where shots generated on the surface up to large ranges are recorded in crustal boreholes.
