Average and standard deviation of ModEM inversions with prior resistivities of 10, 31.6, 69, 100, 316 and 1000 \(\Omega \)m. Black triangles are locations of MT sites. A standard deviation of 0.2 at a certain point in the model means that 68% of the data lie within 0.2 log resistivity of the average value of that cell (averaged across all starting models). For example, average value at a point = 100 \(\Omega \)m (or 2log \(\Omega \)m), St. Dev = 0.2log \(\Omega \)m, and then 68% of values lie within ± 0.2log \(\Omega \)m or between 1.8 and 2.2log \(\Omega \)m or between 65 and 160 \(\Omega \)m. The top row shows the average resistivity values (with 0.5 \(\Omega \)m contours), and the bottom row shows the standard deviation (with 0.2 contours)
