Program sfdvscan2d | Diffraction velocity analysis
[SYNOPSIS]
sfdvscan2d < dataFile_.rsf vel=velFile_.rsf > sembFile_.rsf gn=1 go=1.0 gd=1 coher=11 cigNum=1 dlim=fabs (dipStart_) isSemb=y
[COMMENTS]

Input:
dataFile_.rsf - migrated dip-angle gathers

Output:
sembFile_.rsf - semblance spectrum

[PARAMETERS]
int     | cigNum | =1 |   | 	height of a vertical window for semblance calculation 
int     | coher | =11 |   | 	height of a vertical window for semblance calculation 
float   | dlim | =fabs (dipStart_) |   | 	defines dip-angle-window for the analysis 
float   | gd | =1 |   | 	increment of Vm/V parameter 
int     | gn | =1 |   | 	number of scanned Vm/V values  
float   | go | =1.0 |   | 	start of Vm/V parameter 
bool    | isSemb | =y |  [y/n] | 	y - output is semblance; n - stack power 
string  | vel | = |   | 	velocity model file (velocity in km/s) (auxiliary input file name)
