Recursions for Migration in Slant Frames
, by Bert Jacobs
Profiles require migration operators which handle large dips. One way of doing this is to use a high order migration operator. Another is to use a migration operator aimed to migrate dips centered at a predetermined angle, say in a slanted coordinate system. A simple recursion governs an infinite sequence of increasingly accurate slant migration operators. The first two terms of the sequence are the 15- and 45-degree equation operators.
