Fig. 4: Directional statistics of the directions of asymmetry along the high-level divide.
From: Evolution of eastern Tibetan river systems is driven by the indentation of India

Black lines denote the mean and the upper and lower 95% confidence limits on the mean of the directions. The orange line indicates the direction of the persistent indentation of India. The population of the directions of asymmetry along the high-level divide is shown in the blue histograms.
