WCSREMOVE

Remove co-ordinate Frames from the WCS component of an NDF

Description:

This application allows you to remove one or more co-ordinate Frames  from the WCS  component in an NDF . The indices of any remaining Frames are ‘shuffled down’ to fill the gaps left by the removed Frames.

Usage:

wcsremove ndf frames

Parameters:

FRAMES() = LITERAL (Read
Specifies the Frame(s) to be removed. It can be a list of indices (within the WCS component of the supplied NDF) or list of Domain names. If one or more Domain name are specified, any WCS Frames which have a matching Domain are removed. If a list of indices is supplied, any indices outside the range of the available Frames are ignored. Single Frames or a set of adjacent Frames may be specified, e.g.. typing [4,6-9,12,14-16] will remove Frames 4,6,7,8,9,12,14,15,16. (Note that the brackets are required to distinguish this array of characters from a single string including commas. The brackets are unnecessary when there only one item.) If you wish to remove all the files enter the wildcard ∗. 5-∗ will remove from 5 to the last Frame.
NDF = NDF (Read and Write)
The NDF data structure.

Examples:

wcsremove m51 "3-5"
This removes Frames 3, 4 and 5 from the NDF called m51. Any remaining Frames with indices higher than 5 will be re-numbered to fill the gaps left by the removed Frames (i.e. the original Frame 6 will become Frame 3, etc.).
