FTS1_WCSUT

Removes the spurious copy of the AXIS Frame which is left in WCS component when using non-Native encodings

Description:

This routine removes the Current Frame in the WCS component of an NDF if no value has been set for its Domain attribute, and if it corresponds closely to the AXIS Frame (i.e. if the Mapping from the Current Frame to the AXIS Frame is nearly a UnitMap).

When using non-Native encoding, the AXIS Frame written by NDF2FITS will not have any associated Domain value, and so will not be recognised by the NDF library as an AXIS Frame when it is read back in by FITS2NDF. The Frame will therefore be left in the WCS component of the NDF, even though it is in reality a copy of the AXIS Frame. This routine removes such Frames.

Invocation

CALL FTS1_WCSUT( INDF, STATUS )

Arguments

INDF = INTEGER (Given)
The NDF identifier.
STATUS = INTEGER (Given and Returned)
The global status.
