  1. Details of the five inversions used to determine the best lateral cell size for AusLAMP inversion (5000, 7500 and 10,000 m)
  2. These were run with all the same covariance (0.4) and then with a larger covariance for the 5 km to reduce speckling (0.5) and smaller for the 10 km to get a more detailed model (0.3). The starting RMS is constant, 25.3
