From CLASS

Some CLASS commands directly produce GILDAS images. ANALYSE $\backslash$CUBE produces a spectral line data cube, ANALYSE $\backslash$STRIP an image (either position-velocity, or continuum map). Command ANALYSE $\backslash$GRID produces a pseudo-table which can further be processed to produced a spectral line data cube.

For spectra, tables can be produced by commands ANALYSE $\backslash$GREG, ANALYSE $\backslash$PRINT.
