Figure 1

(top left) distribution of receiver function by 1 degree epicentral distance ranges. (top right) Station informations: number of data, quality of station, travel-time measurements. (bottom left) Seismic section of radial receiver functions stacked by 1 degree event to station distance interval. Hodochrons for seimic phases are also plotted. (bottom right) Stacked receiver function for the station.

Figure 2

(tau,p) diagram for the seismic section below. Black crosses are expected time and slowness for converted waves at 410 and 660 km depth in the IASP91 velocity model (Kennett and Engdhal, 1991).
