Record-valued keywords are used to map an image in the science extension to a distortion array in the ``WCSDVAR extension``. This new type of FITS keywords has been implemented in PyFITS and is fully described in [2]_. Specifically, ``DPj.EXTVER`` in the science extension header maps the science image to the correct ``WCSDVAR`` extension. The dimensionality -- cgit
