Data-cube manipulation

While the initial data-reduction software for IFUs is highly instrument dependent, the data analysis of the final science data product for all these instruments should be fairly generic. The end product of the data reduction for IFS is, almost naturally, an $x$,$y$,$\lambda$ data cube. For instruments not working in the optical and infrared regimes, the third axis may also be in some other spectral co-ordinate system, such as frequency. Once assembled, with associated variance and quality arrays, scientifically interesting information can be extracted from the cube.
