Common Midpoint gather showing the primaries
(shallow two reflections) and the multiples.

With this velocity model I analytically computed the traveltimes of the two primaries and three multiples whose raypaths are shown in Figure . Figure shows a CMP gather with 100 offsets. The first and third events are the primaries and the other are the multiples as evidenced by their reverse polarity. The second event is the water-bottom multiple, the fourth event is the internal multiple, the next one is the peg-leg multiple and the last one is the surface multiple of the deeper reflector.
