Extended Data Fig. 1: Travel-time curves for different Martian core phases.
From: Seismic detection of a 600-km solid inner core in Mars

Light and heavy lines represent travel times for models without and with IC, respectively. The travel times are calculated for a marsquake at a depth of 33 km, using the best “geodynamical” inversion model (SKS_GD model) from ref. 20 as the mode without IC and assuming a + 30% velocity jump across the ICB for the IC model with an IC radius of 618 km.
