Fig. 4From: Seismic wave attenuation (1/Qp) in the crust underneath the Eastern and eastern Southern Alps (Europe): imaging effects of faults, fractures, and fluidsThe assessment of the t* uncertainty by comparison of the t* values of similar ray paths. a The t* values versus their averages along common ray paths. b The histogram of t* deviations from their averages along common ray paths. The standard deviation of ~ 0.015 is assumed to be the t* uncertaintyBack to article page
