In this Appendix, I show that the equations for the non-diffracted multiple
from a dipping water-bottom reduce to the equations for a flat water-bottom
when as they should. Setting in
equations 39 through 42 we obtain

and from equations 5 and 6 we get (as discussed at
the end of Appendix A) and .Therefore,
