Fig. 3: Seismic observations and synthetic waveform fits.
From: Constraints on the martian crust away from the InSight landing site

a The trace on the top panel (in red) is the PP wave train on the vertical component after polarization filtering, and the raw displacement record is also shown in light grey. The waveforms on the middle panel are the synthetic waveforms using the inverted models at the bounce point (shown in Fig. 4c). The seismograms on the bottom panel are synthetics using the receiver-function-derived models at the InSight landing site11 (see Methods section for the synthetic waveform calculation). b Similar to (a), but for the SS wave train on the tangential component.
