NDF_AUNMP - Unmap an NDF axis array   

Description:
The routine unmaps an NDF axis array which has previously been mapped for READ, UPDATE or WRITE access.

Invocation:
CALL NDF_AUNMP( INDF, COMP, IAXIS, STATUS )

Arguments:
INDF = INTEGER (Given)
NDF identifier.
COMP = CHARACTER * ( * ) (Given)
Name of the axis array component to be unmapped: 'CENTRE', 'VARIANCE', 'WIDTH' or '*'. The last value acts as a wild card, causing all mapped axis components to be unmapped.
IAXIS = INTEGER (Given)
Number of the NDF axis whose array is to be unmapped.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:
  • This routine attempts to execute even if STATUS is set on entry, although no further error report will be made if it subsequently fails under these circumstances.
  • A comma-separated list of axis component names may also be given, in which case each component will be unmapped in turn.
  • A value of zero may be supplied for the IAXIS argument, in which case the routine will unmap the specified component(s) for all the NDF's axes.
  • An error will be reported if a component has not previously been mapped for access, except in cases where a wild card unmapping operation is specified (either with a component name of '*' or an axis number of zero).
