The results are displayed in terms of probability density functions (PDFs). Blue and red colours show small and large probabilities, respectively. a,b, Body wave differential times with respect to P waves as a function of tS − tP. Markers and error bars represent observed differential arrival times and their uncertainty, respectively. c–f, tPP − tPdiff (c), tPP − tPbdiffPcP (d) and tSKS − tPP (e,f) as a function of tSS − tPP for event S1000a. The observed differential travel time measurements are displayed with black lines. The pink bands indicate uncertainties on the measurements. Panels a,c,e correspond to the inversion set without a BML, and b,d,f to the inversion set with a BML.
