Describe here algorithm for DMO to real data
One common objection to an exact PSPM is the presence of blind zones when lateral velocity gradients are large (Deregowski, 1986; Hale, 1988). A simple remedy of this problem that we would like to investigate is using PSPM for transforming data not to zero-offset, but to a sufficiently large offset without blind zones, or, if needed, to two different offsets.
