Dear reader,

this is a folder containing data related to Wolf et al. (2021): 3D crustal structure of the Ligurian Sea revealed by surface wave tomography using ocean bottom seismometer data, https://doi.org/10.5194/se-2021-55.

The file Wolf-etal-2021-LigurianSea-supplement.pdf contains additional figures and tables.

The folder contains the following subfolders:

- groupvel-input-lagtimes: FMST input
    the input files for Fast Marching Surface wave Tomography (Rawlinson & Sambridge, 2005)
    contains the traveltime for all possible station pairs. columns: flag (0: unused, 1: used) | lagtime | error

- groupvelmaps-gridfiles: FMST output
    GMT grd-files of the group velocity maps and residuals-per*.dat (see FMST documentation: http://www.iearth.org.au/codes/FMST/instructions.pdf) 

- code-groupvelgrid-to-1Dinput: 
    shell scripts we use to create 1D inversion input from FMST output 
    1D code by Herrmann (2013): http://www.eas.slu.edu/eqc/eqccps.html

- Vs-maps-xyzfiles: 1D inversion output
    layer*-vs.xyz files - resorted 1D inversion output for plotting in map view
    rmserr.xyz contains the RMS value for each grid point 
    plot script is included, additional input files for plotting included

Kind regards,
the authors
