Level 2 data (shear probes)

Level 2 data are the full resolution, cleaned and despiked parameter from level 1. The initial data set is subdivided in sections and labelled accordingly in the parameter SECTION_NUMBER with integers. Level 2 data is ready for estimating spectra, which will be corrected in wavenumber/frequency domain for the spatial averaging of the shear probe and for vibration-coherent content. In addition to cleaned and despiked level 1 data channels, level 2 data comprises the additional parameter summarized in the table below.
