The standard transform (Figures 5a and 5c) was effective in attenuating the specularly-reflected multiples, but failed at attenuating the diffracted multiples (below 4000 m), which are left as residual multiple energy in the primary data.
As stated earlier, working with space images (ADCIGs in this case) is convenient because the migration takes care of the complexity of the wave field propagation, but attenuating the multiples after migration does not come out without a price.
Genome sequence and attenuating
mutations in West Nile virus isolate from Mexico.
PLLs have a jitter transfer function that passes low frequency jitter while attenuating
high frequency jitter.
And where Hockney's photoworks idiosyncratically broke new ground - fracturing perspective and messing with photography's momentariness by attenuating
its frozen flash across a series made into a collage - these new paintings (even the supremely daunting A Bigger Grand Canyon, a vivid sprawl of wet-clay golds, sunset reds, and desert pinks) seem satisfied with gorgeous color and a tug-of-war against the "tyranny of vanishing-point perspective." Many of the paintings become illustrations of his earlier ideas rather than an ongoing exploration.
