Guided by group theory, analysing the invariance-based properties of the fluctuations, our work examines raw time series from hot-wire anemometry measurements in the experiment by Akula et al., JFM 816, 619-660 (2017). The results suggest that the power density spectrum can be modelled as a compound function presented as the product of a power law and an exponential.
