WebMar 27, 2024 · Peak Tailing. Tailing is basically the inverse of fronting. The peak is presented asymmetrically, with a broader second half and a narrower first half – breaking away from the ideal peak shape, with its symmetrical Gaussian profile. While the effect is similar, the circumstances of tailing are different from those of fronting.
