1 MASK_3D
        MASK_3D

      Mask a 3-D data cube based on signal being non-zero
      in another 3-D data cube. Comparison in all axes
      is done based on user coordinates, so data cubes
      do not need to have the same sampling.

      Axis order should match, but there is no compulsory
      ordering of the axes.
