%X Three widely used frequency domain algorithms for post-stack migration are the omega-x, PSPI and explicit algorithms. They differ in speed and accuracy with omega-x being the least accurate and fastest. Phase shift plus interpolation (PSPI) is the slowest and less accurate than the explicit algorithm. The explicit algorithm is the most accurate of the three and its run time falls between the omega-x and PSPI algorithm.
