%
% Post Stack migration
%  FD15MIG: 15 degree finite-difference time migration (2D)
%  FKMIG: Stolt's fk migration (2D)
%  KIRK: simplified Kirchhoff time migration (2D)
%  KIRK_MIG: full-featured Kirchhoff time migration (2D)
%  KIRK_MIG3D: 3D post stack Kirchhoff time migration
%  PS_MIGT: time migration by Gazdag phase shift (2D)
%  PSNSPS_MIG: Exploding reflector depth migration by NSPS (2D)
%  SPLITSTEPF_MIG: Split-step Fourier depth migration (2D)
%  VZ_FKMIG: fk migration for v(z) (2D)
%  VZ_FKMOD: V(z) modelling by an fk technique (2D)
%
% Prestack migration
%  KIRK_SHOT: 2D prestack Kirchhoff migration of a single shot gather
%  KIRK_SHOT3D: 3D prestack Kirchhoff migration of a single shot gather
%  KIRK_SHOT3DFZ: 3D prestack Kirchhoff migration into depth planes. More
%       accurate but slower than KIRK_SHOT3D
%
% Ferguson
% IPS: Isotropic phase shift extraploation (stationary)
%
%
