STM359_grid-02 is derived using SHTOOLS2.4 [1] from 0.250.25 grid data which are then interpolated from the global topographic data obtained during the above period using commands of GMT software (Generic Mapping Tool) [2] 3) Reference [1] Wieczorek M., http:// www.ipgp.jussieu.fr/~wieczor/SHTOOLS/SHTOOLS.html (2007).
