astrometry structure within an NDF. If one is found, THERE is returned true. If one is not found, no
error is reported but THERE is returned false. The name of the extension in which it was
found is returned, together with the name of the astrometry structure, and a locator to the
extension.
Invocation
CALL IRA_FIND( INDF, THERE, XNAME, ASNAME, LOC, STATUS )
Arguments
INDF = INTEGER (Given)
The NDF identifier.
THERE = LOGICAL (Returned)

) (Returned)
The name of the NDF extension in which the astrometry structure was found. Blank if none found.
