Vsv = vertically-polarised shear wave velocity
MEAN = the 2D grid files were built from the ensemble of the 1D mean Vsv profiles  


For 1 km depth increments between 55.5 and 225.5 km, and using 100.5 km depth as an example, this repository holds:  

Vsv_2D_depth100.5km_MEAN_cut.grd : a netcdf grid developed using the Generic Mapping Tools (GMT) holding longitude, latitude, Vsv @ 100.5 km depth
Vsv_2D_depth100.5km_MEAN_cut.xyz : corresponding text file holding columns longitude, latitude, Vsv; Vsv values are NaN beyond the polygon of credible resolution  
Vsv_2D_depth100.5km_MEAN_cut.tif : corresponding tif
Vsv_2D_depth100.5km_MEAN_drapeTOPO.pdf : corresponding pdf image
Vsv_2D_depth100.5km_MEAN_drapeTOPO.png : corresponding png image
Vsv_2D_depth100.5km_MEAN_drapeTOPO.ps  : corresponding ps image

Vsv_2D_depths_55-225km.pdf : the individual pdfs combined for ease of browsing

Vsv_2D_depth_50-225km.xyz : the individual *cut.xyz files combined; columns are depth, longitude, latitude, Vsv; Vsv values are NaN beyond the polygon of credible resolution
Vsv_2D_depth_50-225km_noNaNs.xyz : the individual *cut.xyz files combined; columns are depth, longitude, latitude, Vsv; Vsv values limitied to the polygon of credible resolution
