83 : // <etymology>
84 : // FTMachine is a Machine for Fourier Transforms. Like
85 : // WProjectFT, AWProjectFT does Grid-based Fourier transforms but
86 : // also includes the effects of primary beam and antenna pointing
87 : // offsets.
88 : // </etymology>
89 : //
90 : // <synopsis>
91 : //
92 : // The <linkto class=SkyEquation>SkyEquation</linkto> needs to be
93 : // able to perform Fourier transforms on visibility
94 : // data. AWProjectFT allows efficient handling of direction
95 : // dependent effects due to the primary beam and antenna pointing
96 : // offsets using a <linkto class=VisBuffer>VisBuffer</linkto> which
97 : // encapsulates a chunk of visibility (typically all baselines for
98 : // one time) together with all the information needed for processing
99 : // (e.g. UVW coordinates).
100 : //
101 : // Using this FTMachine, errors due antenna pointing offsets can be
102 : // corrected during deconvolution. One form of antenna pointing
103 : // error which is known a-priori is the VLA polarization squint
104 : // (about 6% of the Primary beam width at any frequency). For
105 : // casacore::Stokes imaging, using this FTMachine, the VLA polarization squint
106 : // and beam polarization can also be corrected. Also since the
107 : // effects of antenna pointing errors is strongest in the range of
108 : // 1-2GHz band (where the sky is not quite empty while the beams are
109 : // not too large either), this FTMachine can also be setup to
110 : // correct for the w-term.
111 : //
112 : // Switches are provided in the get() method to compute the
113 : // derivatives with respect to the parameters of the primary beam
114 : // (only pointing offsets for now). This is used in the pointing
115 : // offset solver.
116 : //
117 : // See the documentation of other FTMachines for details about the
118 : // design of the FTMachines in general.
119 : //
120 : // </synopsis>
121 : //
122 : // <example>
123 : // See the example for <linkto class=SkyModel>SkyModel</linkto>.
124 : // </example>
125 : //
126 : // <motivation>
127 : //
128 : // Encapsulate the correction of direction dependent effects via
129 : // visibility plane convolutions with a potentially different
130 : // convolution function for each baseline.
131 : //
132 : // </motivation>
133 : //
134 : // <todo asof="2005/07/21">
135 : //
136 : // <ul> Include the antenna based complex gain term as well since
137 : // that can interfere with the effects of pointing offsets.
