For hydrophone spectral probability density plot (PNG and PDF) data products only:

Automatic

In this default option, it sets the Y-axis range for the Power Spectral Density to the min/max of the data extended to the next 10 dB interval.

Oceans 2.0 API filter: dpo_spectralProbabilityDensityPSDRange=0

Manual fixed limit settings

This option will cause the spectral probability density plot to use a fixed value, as chosen, for the y-axis range. Using a fixed range is useful for comparing multiple plots.

Oceans 2.0 API filterdpo_spectralProbabilityDensityPSDRange={40_160,20_140,40_140}

File-name mode field

Spectral probability density plots generated with the manual limits will have a file mode modifier added to their file names of the format: <-YLIM><option> where <option> is the value as chosen, with ' to ' replaced by '_'.
