===========================================================
INPUT files for ela2d.x:

	vel_P.dat , vel_S.dat , density.dat	(all binary)
	ela2d.in , grid.param			(all ASCII)

===========================================================
OUTPUT files from ela2d.x:

	seismicX.H@ 	, 	seismicZ.H@
	snapX.H@	, 	snapZ.H@
	wavelet.H@

===========================================================
OUTPUT files for analytical solution computed by 
Cagniard-de Hoop method 
(program by If and Berg, Techn. Univ. Copenhagen, Denmark)

	comp.ux	  (rec. offset=303 m, rec. depth=24 m)
	comp2.uz  (rec. offset=300 m, rec. depth=27 m)	
	comp.ux   (rec. offset=303 m, rec. depth=120 m)
	comp2.uz  (rec. offset=300 m, rec. depth=123 m)
		  (offset and depth are adjusted to the staggered grid
		   formulation ==> different locations for UX and UZ)

	Source point depth: 18 m  

===========================================================
plot.* :  some shellscripts for visualization of the data 
	  with help of SU-package
	  (SU = seismic unix, Colorado School of Mines)

	plot.comp : postscript-plot and -merge the results for the 
		    comparison with the analytical solutions
		==> 'comp.ps'

	plot.seis : X-plots seismograms of 2 receiver lines

	plot.snap : X-movies of the snapshots
