Detection limits of selected core-related arrivals needed to determine core radius and outer core structure. Various curves show the expected acceleration levels expected for a 10¹⁵ N-m source recorded at various ranges (in degrees of great circle arc) from the seismometer. The sensitivity levels of the InSight SP and VBB instruments are shown as horizontal lines (Lognonné et al. 2014). For methods used, see the “Appendix” section
