Status:

application definition, extends NXobject, version 1.0b

Description:

This is an application definition for the final result of a tomography experiment: a 3D construction of some volume of physical properties.

Symbols:

These symbols will be used below to coordinate datasets with the same shape.

nx: number of voxels in X direction

ny: number of voxels in Y direction

nz: number of voxels in Z direction

x[nx]: NX_FLOAT {units=NX_ANY}

This is an array holding the values to use for the x-axis of data. The units must be appropriate for the measurement.

y[ny]: NX_FLOAT {units=NX_ANY}

This is an array holding the values to use for the y-axis of data. The units must be appropriate for the measurement.

z[nz]: NX_FLOAT {units=NX_ANY}

This is an array holding the values to use for the z-axis of data. The units must be appropriate for the measurement.
