This task does an invert of the visibilities and deconvolve in the
        image plane. It does not do a uvdata subtraction (aka Cotton-Schwab
            major cycle) of model visibility as in clean. - For ALMA Commissioning

     vis -- Name of input visibility file
           default: none; example: vis='ngc5921.ms'    

         imagename -- Name of output CASA image. (only the prefix)
               default: none; example: imagename='m2'
               output images are:
             m2.image; cleaned and restored image
                    With or without primary beam correction
             m2dirty.image; dirty image
             m2psf.image; point-spread function (dirty beam)
             m2.model; image of clean components
             m2.mask; image containing clean regions, when interative=True


     field -- Select fields in MS.  Use field id(s) or field name(s).
                ['go listobs' to obtain the list id's or names]
            default: ''= all fields
            If field string is a non-negative integer, it is assumed to
                be a field index otherwise, it is assumed to be a 
                field name
            field='0~2'; field ids 0,1,2
            field='0,4,5~7'; field ids 0,4,5,6,7
            field='3C286,3C295'; field named 3C286 and 3C295
            field = '3,4C*'; field id 3, all names starting with 4C

     spw --Select spectral window/channels
            NOTE: This selects the data passed as the INPUT to mode
            default: ''=all spectral windows and channels
              spw='0~2,4'; spectral windows 0,1,2,4 (all channels)
              spw='0:5~61'; spw 0, channels 5 to 61
              spw='<2';   spectral windows less than 2 (i.e. 0,1)
              spw='0,10,3:3~45'; spw 0,10 all channels, spw 3, 
                                 channels 3 to 45.
              spw='0~2:2~6'; spw 0,1,2 with channels 2 through 6 in each.
              spw='0:0~10;15~60'; spectral window 0 with channels 
                                  0-10,15-60
              spw='0:0~10,1:20~30,2:1;2;3'; spw 0, channels 0-10,
                    spw 1, channels 20-30, and spw 2, channels, 1,2 and 3

    imsize -- Image pixel size (x,y).  DOES NOT HAVE TO BE A POWER OF 2
               default = [256,256]; example: imsize=[350,350]
               imsize = 500 is equivalent to [500,500]
               Avoid odd-numbered imsize.

    cell -- Cell size (x,y)
               default= '1.0arcsec';
               example: cell=['0.5arcsec,'0.5arcsec'] or
               cell=['1arcmin', '1arcmin']
               cell = '1arcsec' is equivalent to ['1arcsec','1arcsec']
               NOTE:cell = 2.0 => ['2arcsec', '2arcsec']

    phasecenter -- direction measure  or fieldid for the mosaic center
               default: '' => first field selected ; example: phasecenter=6
               or phasecenter='J2000 19h30m00 -40d00m00'

    niter -- Maximum number iterations,
               if niter=0, then no CLEANing is done ("invert" only)
               default: 500; example: niter=5000

    weighting -- Weighting to apply to visibilities:
               default='natural'; example: weighting='uniform';
               Options: 'natural','uniform','briggs', 
                       'superuniform','briggsabs','radial'

    restoringbeam -- Output Gaussian restoring beam for CLEAN image
               [bmaj, bmin, bpa] elliptical Gaussian restoring beam
               default units are in arc-seconds for bmaj,bmin, degrees
               for bpa default: restoringbeam=[]; Use PSF calculated
               from dirty beam. 
               example: restoringbeam=['10arcsec'] or restorinbeam='10arcsec', circular Gaussian.
                        FWHM 10 arcseconds example:
                        restoringbeam=['10.0','5.0','45.0deg'] 10"x5" 
                        at 45 degrees
    
        interactive -- Create a mask interactively or not.
                       default=False; example: interactive=True
                       The viewer will open with the image displayed. Select the
                       region for the mask and double click in the middle of it.
