\n Synopsis
		sfdagap3 < dagFile.rsf dips=dipFile.rsf > taperFile.rsf ddep=y pwidth1=10.f pwidth2=10.f greyarea1=10.f greyarea2=10.f dz=20.f

\nMay be used for migration aperture optimization or for reflected energy
\nsupression. For the last multiply the output on -1.
\n
\nInput:
\ndagFile.rsf - input dip-angle gathers;
\ndipFile.rsf - dips esitimated in the image domain. The dips are in degree (!)
\n
\nOutput:
\ntaperFile.rsf - mask for input dip-angle gathers
