The dimension (or index) of the data hyper-cube which is not to be used as loop-index when plotting all the selected data. Usually corresponds to X-axis selection, i.e. it is "pt" for "Time", or "ch" for channel/wavelength, etc. If plotting visibilities vs channel index, for example, selecting "ch" as slice would produce one plot per scan, unless the "All in 1" option is selected.

The English Channel is one of the world's most extraordinary pieces of water. ... Sailors know it as perhaps the most dangerous sea channel in Europe. ... The Channel stretches 350 miles, from the Atlantic ocean to the North sea, separating England's south coast from France's north coast. ... It must be mentioned that the sea in the Channel is usually cold, and swimmers must cover their bodies with grease to protect their bodies. ... But swimming enthusiasts are not stopped by the difficulties. ...

Fabry-Perot data cubes. Introduction: what is "data cubes"? Observations with the IFP consist of successive acquisition of a few dozen images of interference rings from the object (or from a calibration lamp) when changing the optical path between the flat-parallel plates. The radius of the rings is a function of wavelength and gap between the plates of the interferometer. ... Its interference rings of Ne line which use for phase calibration (convert object data to wavelength-scale). ...

... Next, consider a more elaborate UBVRI photometer with two channels (a ``red'' and a ``blue'' tube). We suppose it has separate filter wheels in the two beams; the first filter wheel contains the UBV filters, and the second has the R and I filters. ... If the filter wheels had been in series instead of in separate beams, the unused wheel would have to be set to a clear position, instead of the ``any'' entered in the first five lines of Table . ...
