Help on exportfits task:
 
Convert a CASA image to a FITS file
 
        CASA-produced images can be written to disk for transporting
        to other software packages.  No subimaging of the fits image
        can be made with this task.
 
        Keyword arguments:
        imagename -- Name of input CASA image
                default: none; example: imagename='3C273XC1.image'
        fitsimage -- Name of ouput image FITS file
                default: none; example='3C273XC1.fits'
        velocity -- Use velocity (rather than frequency) as spectral axis
                default: False
        optical -- Use the optical (rather than radio) velocity convention
                default: False;
        bitpix -- Bits per pixel
                default: -32 (floating point)
                <Options: -32 (floating point), 16 (integer)>
        minpix -- Minimum pixel value
                default: 0 = autoscale
        maxpix -- Maximum pixel value
                default: 0 = autoscale
        overwrite -- Overwrite pre-existing imagename
                default=False; example: overwrite=True
        dropstokes -- Drop Stokes axis?
                default: False; example: dropstokes=True
        stokeslast -- Put Stokes axis last in header?
                default: True; example: syokeslast=False
        async --  Run asynchronously
                default = True; recommended.
