Existing constraints on disk turbulence from submm line broadening αline (Rosotti 2023, and references therein), the inferred αfrag by assuming pebble size is limited by fragmentation (this work), and the αgap constrained from dust settling (Doi & Kataoka 2021; Liu et al. 2022; Pizzati et al. 2023).
