Datasets for mode decomposition in ducts

I am providing two datasets to facilitate the development of mode decomposition algorithms for flow ducts. The measurements were conducted using a carefully constructed and validated measurement setup at the Marcus Wallenberg Laboratory for Sound and Vibration Research at KTH in Stockholm, Sweden under the supervision of Prof. Mats Åbom. Along with the data, I also provide examples of mode decomposition with the package Acdecom in the scripting language Python.
