  // <summary>  An FTMachine for Gridded Fourier transforms including effects of primary beam and pointing offsets and the w-term</summary>

  // <etymology> 
  // FTMachine is a Machine for Fourier Transforms. Like
  // WProjectFT, AWProjectFT does Grid-based Fourier transforms but
  // also includes the effects of primary beam and antenna pointing
  // offsets. 
  // </etymology>
  //
  // <synopsis> 
  //
  // The <linkto class=SkyEquation>SkyEquation</linkto> needs to be
  // able to perform Fourier transforms on visibility
  // data. AWProjectFT allows efficient handling of direction
  // dependent effects due to the primary beam and antenna pointing
  // offsets using a <linkto class=VisBuffer>VisBuffer</linkto> which
  // encapsulates a chunk of visibility (typically all baselines for
  // one time) together with all the information needed for processing
  // (e.g. UVW coordinates).
  //
  // Using this FTMachine, errors due antenna pointing offsets can be
  // corrected during deconvolution.  One form of antenna pointing
  // error which is known a-priori is the VLA polarization squint
  // (about 6% of the Primary beam width at any frequency).  For
  // casacore::Stokes imaging, using this FTMachine, the VLA polarization squint
  // and beam polarization can also be corrected.  Also since the
  // effects of antenna pointing errors is strongest in the range of
  // 1-2GHz band (where the sky is not quite empty while the beams are
  // not too large either), this FTMachine can also be setup to
  // correct for the w-term.
  //
  // Switches are provided in the get() method to compute the
  // derivatives with respect to the parameters of the primary beam
  // (only pointing offsets for now).  This is used in the pointing
  // offset solver.
  //
  // See the documentation of other FTMachines for details about the
  // design of the FTMachines in general.
  //
  // </synopsis> 
  //
  // <example>
  // See the example for <linkto class=SkyModel>SkyModel</linkto>.
  // </example>
  //
  // <motivation>
  //
  // Encapsulate the correction of direction dependent effects via
  // visibility plane convolutions with a potentially different
  // convolution function for each baseline.
  //
  // </motivation>
  //
  // <todo asof="2005/07/21">
  //
  // <ul> Include the antenna based complex gain term as well since
  // that can interfere with the effects of pointing offsets.  
  //
  // <ul> Factor out the actual convolution functions as a separate
  // class making FTMachines for various direction dependent effects
  // generic.
