This data publication contains the data for the publication "Benchmarking a magnon-scattering reservoir with modal and temporal". The dataset is structured in folders corresponding to the different figures in the paper. The parent folder contains the full BLS spectrum and the input used to generate that spectrum. Folder Fig2 contains the experimental data measured with Brillouin-light-scattering microscopy integrated for the measured positions. Fig3 and Fig4 contain the extraction and evaluation. Each Folder contains additional information about their content.
