Fig. 6

Array positions projected as bars as a function of observation position.

A bar represents the horizontal deviation of array positions (\( \sqrt{{\delta x}^2+{\delta y}^2} \)) based on (a) buoy-based observation and (b) ship-based observation. The black bar located at the bottom left in each panel indicates a deviation scale of 1 m deviation. The blue bars correspond to observation positions outside the array, and the red bars correspond to observation positions inside the array. The orientations of the bars indicate the orientations of array positions relative to the initial position
