New Commands

The following new applications have been added:

PLUCK

This extracts slices parallel to pixel axes from an NDF. The slices are nominated positions that are not at pixel centres. Thus it can be used for example, with a spectral imaging cube to extract spectra at specified equatorial co-ordinates, or an image at a given spectral co-ordinate.

PROVADD

This modifies the provenance information stored in an NDF. It records a second specified NDF as a direct parent of the first NDF.

PROVSHOW

This displays details of the NDFs that were used in the creation of a supplied NDF. This information is read from the PROVENANCE extension within the NDF, and includes both immediate parent NDFs and older ancestor NDFs.
