Reflection event apex protector/removal for dip-angle gathers.

 
Synopsis
        sfdagap < dagFile.rsf dips=dipFile.rsf > taperFile.rsf ddep=y pwidth=10.f greyarea=10.f dz=20.f

May be used for migration aperture optimization or for reflected energy
supression. For the last multiply the output on -1.

Input:
dagFile.rsf - input dip-angle gathers;
dipFile.rsf - dips esitimated in the image domain. The dips are in degree (!)

Output:
taperFile.rsf - mask for input dip-angle gathers

 
Parameters
       
 
bool ddep=y [y/n]
if y, taper depends on depth; if n, no
 
string dips=
dips esitimated in the image domain (in degree) (auxiliary input file name)
 
float dz=20.f
half of a migrated wave length
 
float greyarea=10.f
width of event tail taper (in degree)
 
float pwidth=10.f
protected width (in degree)
