Fig. 4From: Pn tomographic velocity and anisotropy beneath the Tibetan Plateau and the adjacent regionsCheckerboard test result for velocity (a) and anisotropy (b). Checkerboard size is 2.0° × 2.0° for velocity and anisotropy. The isopleths in Fig. 4(a) are pointing −0.3, −0.15, 0.0, 0.15 and 0.3 km/s velocity anomaly.Back to article page
