The files layer_XX.grd contain the same model as .grd-files. The 8 layers of the model correspond to the following depth ranges: 0- 40 km : layer01 40-100 km : layer02 100-160 km : layer03 160-240 km : layer04 230-320 km : layer05 320-410 km : layer06 410-530 km : layer07 530-660 km : layer08 A GMT script 'plot_layers.gmt' is provided to plot horizontal slices of the velocity anomalies. More information on the final model and a suggested set of interpretations can be found in: Braszus, B., et al. (2021), Subduction history of the Caribbean from upper-mantle seismic imaging and plate reconstruction, Manuscript in revision for Nature Communications. Further details of the method and tests for an earlier version of the model are in: Braszus, B.
