Fig. 6: Differential time structure sensitivity kernels for different station triplets.

The sensitivity kernel is normalized between −1 and 1. A Structure kernel for virtual source N101 and receiver pair 21–23. Station N101 is in the SW corner of the LASSIE array. Stations are numbered consecutively from SW corner. B Structure kernel for virtual source N101 and receiver pair 25–27. C Combined sensitivity kernel for the virtual source N101 and all station triplets.
