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. ...

... The processing of these associated images presents new challenges to the HST data processing pipelines, which heretofore operated only on single images. ... Stage 1 (CALNICA) calibrates individual exposures without information from other members of the association. ... Stage 2 of calibration (CALNICB) only operates on associated images that have previously gone through CALNICA processing, and creates combined images for each distinct (non-overlapping) pointing within the association. ...
