Δt * as a function of offset (shot-receiver distance). Points with vertical and horizontal bars indicate the estimated Δt* from the spectral ratios shown in Figure 5. Horizontal bars indicate the range of offsets of stacked traces used to estimate the corresponding Δt*, and vertical bars indicate the uncertainties in Δt*. Solid circles indicate the Δt* values calculated by the best-fit Q P values shown in Table 1. Colored circles and squares are expected Δt* of the refracted waves from L3 and the reflected waves from the megasplay fault, respectively. Blue, red, and green symbols are for models with Q P = 100, Q P = 349, and Q P = 2,000 in L3, respectively.
