Introduction
The supplemental text for this manuscript provides additional details on receiver
function computation, H-k stacking, and error analysis. The discrepancy between
wide-angle and receiver function Vp/Vs estimates is briefly discussed. The
supplemental figures provide examples of receiver function gathers, stacked
receiver function traces, and H-k stacks. A map of Ps delay times is also presented
for comparison with Figure 4 in the main text. The supplemental tables show the
results of H-k stacking and Ps-delay time estimates of crustal thickness for selected
SESAME and TA stations.

stacking, and error analysis. A brief discussion about the effects of refraction
on wide-angle Vp/Vs estimates is also included.
