The surface-consistent conditions do not require that the static shifts, attenuation, and so on are the same when a geophone is located at point P as when the source is located at P. Although the amount of time shift to be associated with any trace might not be known, crosscorrelation methods give a way of finding the time shift of one trace relative to that of another. Such a shift produces the optimum alignment of the two traces.
