Comparison of error ellipses (Fig. 7) with those calculated from synthetic testing.
a The black ellipses are the same as those in Fig. 7. The red ellipses are 95% confidence ellipses calculated from array positions in a synthetic test. The gray circle is the range within which the sea surface platform exists using our mooring buoy system. b An example of array positions and the corresponding 95% confidence ellipse, calculated through 1000 repetitions of a synthetic test for the position (2.5 km, − 2.0 km) in Fig. 9a surrounded by a blue square
