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.

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). ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...
