The Cartesian coordinates of the model are referred to the origin point 
(at 10.2° E and 44.6° N) and are obtained from geographical coordinates
using the UTM (Universal Transverse Mercator) projection (zone 33N). 
z increases with depth below sea level.

Interfaces are:
- T: topography
- BS: the bottom of the sedimentary layer
- MO1: Moho defined by a continuous surface
- MO2: segmented Moho

The geophysical parameters of the crust are:
- Vp: velocity of P-wave (km/s)
- Vs: velocity of S-wave (km/s)
- rho: density (10^3 kg/m^3)
- mu: shear modulus (10^9 N/m^2)
- young: young modulus (10^9 N/m^2)

The errors of interfaces and parameters are the total errors (see paper for a complete description).
