MARVEL®: Mute Module

The mute module mutes above, below, or along a linearly-interpolated curve whose width is defined by the times in the mute file, or by the mute X and T values. Mute values are extrapolated to the left by the smallest time sample on the trace, and to they are extrapolated to the right by the last value given in the various mute arrays. (For the purposes of this program, above means shorter time and below means longer time as would normally be seen on a seismic section.) The linear option allows you to define a corridor around a central line to remove air-blasts or other linear events from the gather. In this case, the mute is defined by the linear velocity parameter.
