The time difference (often described by the number of data samples) between an input value and the prediction based on it. For example, reverberation multiples in a surface water layer are delayed by the two-way traveltime in the water layer, so the deconvolution operator has this prediction lag and the operator does not begin functioning until after this lag time (also called a gap, as in gapped deconvolution).
