Aperture optimization for migrated gathers in the dip-angle domain.

 
Synopsis
        sfdiptaper < dipFile.rsf > taperFile.rsf dz=20.f greyarea=10.f

Estimates a constructive imaging part of a reflection event in the dip-angle domain.
Basing on the estimation defines a stacking weight for every migrated sample.

Input:
dipFile.rsf - dips esitimated in constant-dip subimages. The dips are in degree (!).
A positive dip corresponds to an ascending boundary, a negative dip - to a descending boundary.
A constant-dip subimage consists of migrated traces correspondig to the same dip-angle.

Output:
taperFile.rsf - optimal weights for the migrated samples

 
Parameters
       
 
float dz=20.f
half of a migrated wave length
 
float greyarea=10.f
width of event tail taper (in degree)
