90 : // FTMachine is a Machine for Fourier Transforms. Like
91 : // WProjectFT, AWProjectFT does Grid-based Fourier transforms but
92 : // also includes the effects of primary beam and antenna pointing
93 : // offsets.
94 : // </etymology>
95 : //
96 : // <synopsis>
97 : //
98 : // The <linkto class=SkyEquation>SkyEquation</linkto> needs to be
99 : // able to perform Fourier transforms on visibility
100 : // data. AWProjectFT allows efficient handling of direction
101 : // dependent effects due to the primary beam and antenna pointing
102 : // offsets using a <linkto class=VisBuffer>VisBuffer</linkto> which
103 : // encapsulates a chunk of visibility (typically all baselines for
104 : // one time) together with all the information needed for processing
105 : // (e.g. UVW coordinates).
106 : //
107 : // Using this FTMachine, errors due antenna pointing offsets can be
108 : // corrected during deconvolution. One form of antenna pointing
109 : // error which is known a-priori is the VLA polarization squint
110 : // (about 6% of the Primary beam width at any frequency). For
111 : // casacore::Stokes imaging, using this FTMachine, the VLA polarization squint
112 : // and beam polarization can also be corrected. Also since the
113 : // effects of antenna pointing errors is strongest in the range of
114 : // 1-2GHz band (where the sky is not quite empty while the beams are
115 : // not too large either), this FTMachine can also be setup to
116 : // correct for the w-term.
117 : //
118 : // Switches are provided in the get() method to compute the
119 : // derivatives with respect to the parameters of the primary beam
120 : // (only pointing offsets for now). This is used in the pointing
121 : // offset solver.
122 : //
123 : // See the documentation of other FTMachines for details about the
124 : // design of the FTMachines in general.
125 : //
126 : // </synopsis>
127 : //
128 : // <example>
129 : // See the example for <linkto class=SkyModel>SkyModel</linkto>.
130 : // </example>
131 : //
132 : // <motivation>
133 : //
134 : // Encapsulate the correction of direction dependent effects via
135 : // visibility plane convolutions with a potentially different
136 : // convolution function for each baseline.
137 : //
138 : // </motivation>
139 : //
140 : // <todo asof="2005/07/21">
141 : //
142 : // <ul> Include the antenna based complex gain term as well since
143 : // that can interfere with the effects of pointing offsets.
144 : //
145 : // <ul> Factor out the actual convolution functions as a separate
