SYNOPSIS

SEISMIC UNIX NOTES SUIMP2D - generate shot records for a line scatterer

           embedded in three dimensions using the Born	

	    integral equation				",							



 suimp2d [optional parameters] >stdout

 Theory: Use the 3D Born integral equation (e.g., Geophysics,

 v51, n8, p1554(7)). Use 2-D delta function for alpha and do

 remaining y-integral by stationary phase.



 Note: Setting a 2D offset in a single offset field beats the

       hell out of us.  We did _something_.



 Trace header fields set: ns, dt, tracl, tracr, fldr, sx, selev,

                          gx, gelev, offset
