[OpendTect_Users] Sweetness Attribute

[Christopher P. Ross]

Rene,

Assuming that the numerator is nearly the same measure of reflection 
strength in both equations, the question comes down to how close the 
instantaneous frequency approaches the average.  I personnaly use the 
average frequency that tends to vary more slowly, but both equations 
should give you a relative answer of where better, more homogeneous 
reservoirs are.
