The FK_FILT module can be used to truncate the FK-spectrum either by a dip filter (specify DIP, ignore VERTICES) in which all events with dip > DIP (in ms/trace) are removed, or by defining a polygon containing the filter reject- or pass-band (leave DIP blank, and enter the vertices of the polygon).
The FKMUTE module can be used to mute the FK spectrum of the supplied data either at, above or below a polyline, or inside or outside a polygon. This will probably be the easiest module to define for linear noise attenuation. Some may think that FK muting is not AVO friendly - however if you're careful with the tapering this shouldn't be an issue. You could also try Tau-P domain muting, though this may be slightly more complicated to set-up. Both should give you a reasonable result for linear noise attenuation.
