Reply to Comment on “Amplitude of waves in the Kelvin-wave cascade” (Pis'ma v ZhETF 111, 462 (2020))

This is a Reply to Sonin's Comment [arXiv preprint arXiv:2003.09912, 2020] on Eltsov and L'vov [Pis'ma v ZhETF 111, 462 (2020)] in which we provide relation of the energy flux carried by the cascade to the amplitude of the excited Kelvin waves, important for analysis of future experiments.
