      - to edit the z-axis of the cube (e.g. to compress the cube to a single layer or strech it). NOTE: by doing this action no beam convolution is taken into account. We assume that every channel has the same beam size. Only in the Beta release there will be the opportunity to create a moment-0 map of the cube.and thus a proper convolution will be done (if different channels have different beams).
