PSTM definition

PSTM means Pre-Stack Time Migration, a form of migration that has the effect of moving dipping events on a surface seismic line from apparent locations to their true locations in time. The resulting image is shown in terms of travel time rather than depth, and must then be converted to depth with an accurate velocity model;
