title: Deformation of a Peregrine soliton by fluctuating backgrounds.
abstract: A generalized Peregrine soliton moving on a fluctuating background is constructed. The agreement with the experimental results is improved compared to the standard Peregrine soliton. It has a deformed shape asymmetric with respect to time, and the peak values are not always 3.
