which is the same as equation (G-5). This means that 3-D migration can be performed in two passes: 2-D migration in the inline direction followed by 2-D migration in the crossline direction. The above derivation of a 90-degree 3-D migration operator Levin [1] is based on the constant-velocity assumption.
