Time-distance (T-X) curves Single horizontal layer

Time-distance (T-X) curves Single horizontal layer. T 2 = T 0 2 + X 2 /V 2 . It is a hyperbola with apex at X = 0 and T 0 = 2H/V. V and H are the layer velocity and thickness. T 2 -X 2 plot is a straight line whose slope = 1/V 2 and intercept = T 0 2 .
