This processed data is from TEAMER testing through RFTS 7 at the O.H. Hinsdale Wave Research Laboratory in Corvallis, Oregon. This testing was conducted by Oregon State University (OSU) and Sandia National Laboratories in October and November 2023. The Laboratory Upgrade Point Absorber (LUPA) WEC was used for experimental testing in the large wave flume with a water depth of 3.695 m in the six-DOF configuration. These results processed 4 undisturbed regular wave conditions, each repeated 10 times for a total of 40 trials. The type A (statistical) uncertainty is evaluated for wave height and period. The provided Excel and mat files are the processed data for each trial as defined by the metadata and the column headers. The plotTEAMER_Uncertainty_postAccessReport.m MATLAB file processes the provided mat file to make the figures in the Post Access Report. The mat file has more detailed data for wave-by-wave analysis of each trial. This project is part of the TEAMER RFTS 7 (request for technical support) program.
