Methodology to evaluate the uncertainty of AVA attributes

We will use multiple equal-probable velocity models to get multiple images. From those images, we can extract angle gathers and get intercept A and slope B Gratwick (2001). By comparing and contrasting the multiple realizations of these AVA attributes, we can access their variability.
