NDF_PTWCS
- Store world coordinate system information in an NDF
- Description:
The routine stores new world coordinate system (WCS) information
in an NDF, over-writing any already present.
- Invocation:
CALL NDF_PTWCS( IWCS, INDF, STATUS )
- Arguments:
-
IWCS = INTEGER (Given)
-
An AST pointer to a FrameSet (SUN/210) containing information
about the new world coordinate systems to be associated with
the NDF.
-
INDF = INTEGER (Given)
-
NDF identifier.
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
-
This routine may only be used to store WCS information in a
base NDF. If an NDF section is supplied, it will simply return
without action.
-
The AST FrameSet supplied must conform to the various
restrictions imposed by the NDF_ system (e.g. on the nature of
its base Frame). An error will result if any of these
restrictions is not met.
-
This routine makes a copy of the information in the FrameSet
supplied, so the original FrameSet may subsequently be modified
without affecting the behaviour of the NDF_ system.
