Choose the length of data (in meters) used for each dissipation estimate – diss-length.
Choose the lowest wavenumber of spectral estimation – fft-length.
Translate diss-length and fft-length into duration (time).
Round these up to nearest power-of-two number of samples.
Choose a high-pass filter cut-off frequency to be consistent with duration of the fft-length.
Choose de-spiking parameters.
Choose vibration-coherent noise removal.

Please note that most choices made must be included in a data set, as described in the list of meta data.
