The attitude of long-path multiples does not represent the portion of the section associated with their arrival time. Usually long-path multiples have traveled more in the slower (shallower) part of the section than primaries with the same arrival time, so that they ordinarily show more normal moveout and can be attenuated by common-midpoint stacking.[1].
