A typical radio dataset might be a 3-dimensional "cube" named AURORA, with axes RA, DEC and FREQ. ... These can be specified by giving the axis name(s) and grids for each subset. For instance, AURORA specifies the whole 3-dimensional ``cube''; AURORA FREQ 3 specifies the subset FREQ=3 (i.e. the RA-DEC plane at FREQ grid 3) of the set AURORA. ... Specifying only the axis name, and no grids, selects all subsets along that axis: AURORA FREQ selects all RA-DEC planes in AURORA. ... axis centre. ...
