MSNoise-Tomo

MSNoise-Tomo is a plugin to the MSNoise framework, allowing to branch from the REF stack to compute FTAN, dispersion curves and 2D period maps.

MSNoise-Tomo is developed by Thomas Lecocq (Royal Observatory of Belgium, ROB) based on original codes from A. Mordret and M. Landès (IPGP, 2013).
