Webexploding reflector model, the energy is proportional to the reflectivity of the interfaces. This heuristic or ad hoc approach to migration coincides with the Kirchhoff integral solution to the wave equation. The reflectivity coefficients vary with the angles of incidence, reflection and transmission. http://sepwww.stanford.edu/data/media/public/docs/sep140/claudio1/paper_html/index.html cynthia\u0027s sewing center bend oregon
