VMOD Array

The VMOD array is a simple means to represent a seismic layer structure stored in a .nd file. The VMOD array does not allow to store discontinuity name information.

The VMOD type is merely a historical artefact, but may be useful when converting machine generated models (or models from other sources) into model structures and .nd files.

VMOD Array
Field Type Units Description
vmod[:,1] numeric array km specifies the depth of the upper boundaries of all layers in model. vmod[1,1] is the top of the uppermost layer.
vmod[:,2] numeric array km/s P wave velocities at depths specified in vmod[:,1].
vmod[:,3] numeric array km/s S wave velocities at depths specified in vmod[:,1].
vmod[:,4] numeric array g/cm3 Density at depths specified in vmod[:,1].
vmod[:,5] numeric array dimensionless P wave quality factor at depth specified in vmod[:,1].
vmod[:,6] numeric array dimensionless S wave quality factor at depth specified in vmod[:,1].
