Description

Gathers statistics for surface consistent algorithms

 

The module does two things: build statistics and calculate surface statistics amplitude and phase for surface consistent statics algorithms. These two parts can be run separately one by one using verbs or can be run all at once. Results of the procedure can be used by SC Decon procedure or SC frequency amplitude correction procedure. For building statistics frequency range is divided into part and for each part statistics is built. The procedure has graphical views that shows results of its work: location map, gathers view, spectrum histogram and amplitude-frequency spectrum.
