    """
    Create a new FITS file using the supplied data/header.
    Patched version of pyfits to correctly include provided header

    Parameters
    ----------
    filename : file path, file object, or file like object
        File to write to.  If opened, must be opened in a writeable binary
        mode such as 'wb' or 'ab+'.

    data : array, record array, or groups data object
        data to write to the new file

    header : `Header` object, optional
        the header associated with ``data``. If `None`, a header
        of the appropriate type is created for the supplied data. This
        argument is optional.

    output_verify : str
        Output verification option.  Must be one of ``"fix"``, ``"silentfix"``,
        ``"ignore"``, ``"warn"``, or ``"exception"``.  May also be any
        combination of ``"fix"`` or ``"silentfix"`` with ``"+ignore"``,
        ``+warn``, or ``+exception" (e.g. ``"fix+warn"``).  See :ref:`verify`
        for more info.

    clobber : bool, optional
        If `True`, and if filename already exists, it will overwrite
        the file.  Default is `False`.

    checksum : bool, optional
        If `True`, adds both ``DATASUM`` and ``CHECKSUM`` cards to the
        headers of all HDU's written to the file
