Sign-count stacking velocity analysis, slant stacks, and beam stacks
, by Rick Ottolini
Sign-count stacking counts the number of same polarity samples to a stack rather than
summing the samples together. Given a wide enough summation aperture, sign-count stacking
has similar signal discrimination as conventional stacking, but superior aliasing and
edge control. It made slight improvements in stacking velocity analysis and beam stacks.
Slant stacks were worse because relatively few traces contribute to each stack.
