| dc.description | **Introduction** This folder structure contains the relevant references to data and scripts used for the following publication: Steffen Bisswanger, Henning Bonart, Pyi Thein Khaing, and Steffen Hardt. "Liquid Surfaces with Chaotic Capillary Waves Exhibit an Effective Surface Tension." Physical Review Letters 133, no. 3 (2024): 034001 Please follow the publication to understand the experimental setup and the procedure for data evaluation. **Experimental raw data** Due to the size of the raw data, it is only available upon request from the authors, and not deposited on the public repository except from the data corresponding to a single experimental run as an example. The experimental data has the following structure: Naming scheme: YYMMDD/ ├─ session_xx/ │ ├─ run_01/ │ │ ├─ YYMMDD_sxx_r01.nd2 # contains raw image data (1 fps); proprietary format readable with imagej plugin │ │ ├─ jpg/ # contains unpacked frames (.jpg-files) │ │ ├─ eval/ # contains marked holes to check post processing for screw-ups (.jpg-files) │ │ ├─ YYMMDD_sxx_r01.csv # contains raw data from laser line sensor │ │ ├─ eval.csv # contains the evaluated data of the experiment, including wave energy density measurement │ │ ├─ energy_density_spectra_rel.csv # contains the energy density spectra for each point in the laser line (rel = rigid body motion of substrate is already substracted) │ │ ├─ spectrum_noise_reduction_rel.csv # contains the (over many points on the laser line) averaged spectrum, with white noise background substraction applied │ │ ├─ │ ├─ run_02/ │ ├─ ... │ ├─ run_11/ │ ├─ vibration_data/ Each session is conducted at a constant volume (except from the experiments with constant amplitude available upon request). Each run can be seen as a quasi static experiment corresponding to a specific set of parameters. The folder "YYMMDD_sxx_vibration_data" is session-specific amd contains the vibration data (frequency and amplitude) corresponding to all the runs. **Scripts to process and evaluate experimental data as well as to obtain numerical solutions** - iso_lc_data - Contains the script used for calculating the iso lc-lines (constant capillary length) shown in figure 2. - wave energy measurement - Contains the scripts used for the postprocessing of the laser sheet sensor data, giving the wave energy density measurement. - bayesian_inference Contains the scripts for the inference of the capillary lengths from the experimental data used for figure 5 including the forward model, its surrogate model, likelihood functions, Bayesian inference via ADVI, as well as the visualization of intermediate results and the figures in the supplemental material. ** results.csv ** Contains the summarized results.
