89 : // <synopsis>
90 : // The <linkto class=SkyEquation>SkyEquation</linkto> needs to be able
91 : // to perform Fourier transforms on visibility data. FTMachine
92 : // allows efficient Fourier Transform processing using a
93 : // <linkto class=VisBuffer>VisBuffer</linkto> which encapsulates
94 : // a chunk of visibility (typically all baselines for one time)
95 : // together with all the information needed for processing
96 : // (e.g. UVW coordinates).
97 : // </synopsis>
98 : //
99 : // <example>
100 : // A simple example of a FTMachine is found in
101 : // <linkto class=GridFT>GridFT</linkto>.
102 : // See the example for <linkto class=SkyModel>SkyModel</linkto>.
103 : // </example>
104 : //
105 : // <motivation>
106 : // Define an interface to allow efficient processing of chunks of
107 : // visibility data
108 : //
109 : // Note that the image must be Complex. It must contain the
110 : // casacore::Complex casacore::Stokes values (e.g. RR,RL,LR,LL). FTMachine
111 : // uses the image coordinate system to determine mappings
112 : // between the polarization and frequency values in the
113 : // casacore::PagedImage and in the VisBuffer.
