1. A method for correcting an input seismic trace, comprising: receiving the input seismic trace; creating, using a computer, a t by Q gather using the input seismic trace, wherein t represents traveltime, Q represents absorption parameter, and the t by Q gather has traveltime as the vertical axis and a ratio of t and Q as the horizontal axis, wherein the ratio of t and Q is referred to as R; and applying an interpolation algorithm to the t by Q gather to derive a corrected input seismic trace.
