CRS-based semblance for 3D

 
Synopsis
        sfcrssemb3d < inDags_.rsf dataSq=inDagsSq_.rsf > sembFile_.rsf xapp=1 yapp=1 dipappx=11 dipappy=11 coher=11 scatnum=1
Several CIGs are used simultaneously. Dip-angle sections corresponding to the same
dip-angle compose a subvolume. The subvolume allows calculating semblance in the
scattering-angle direction along reflection boundaries.

Input:
inDags_.rsf - 3D dip-angle gathers - stack in the scattering-angle direction
inDagsSq_.rsf - stack of amplitude squares in the scattering-angle direction

Working with just dip-angle gathers use default value of "scatnum" parameter

Output:
sembFile_.rsf - crs-based semblance file; has the same dimensions as the input files

 
Parameters
       
 
int coher=11
height of a vertical window for semblance calculation
 
file dataSq=
auxiliary input file name
 
int dipappx=11
number of traces in the x-dip direction processed simultaneously
 
int dipappy=11
number of traces in the y-dip direction processed simultaneously
 
int scatnum=1
shows how many traces were stacked in the scattering angle direction;
if the stack was normalized use the default value

 
int xapp=1
number of CIGs in the inline-direction processed simultaneously
 
int yapp=1
number of CIGs in the crossline-direction processed simultaneously
