Fig. 3From: Pn tomographic velocity and anisotropy beneath the Tibetan Plateau and the adjacent regionsDistribution of residuals versus epicentral distance before inversion (a) and after joint velocity and anisotropy inversion (b). The standard deviation of Pn traveltime residuals is 2.0 s for the original data and decreases to 1.1 s after inversion.Back to article page
