75 : // FTMachine is a Machine for Fourier Transforms. SDGrid does
76 : // Single Dish gridding in a similar way
77 : // </etymology>
78 : //
79 : // <synopsis>
80 : // The <linkto class=SkyEquation>SkyEquation</linkto> needs to be able
81 : // to perform Fourier transforms on visibility data and to grid
82 : // single dish data.
83 : // SDGrid allows efficient Single Dish processing using a
84 : // <linkto class=VisBuffer>VisBuffer</linkto> which encapsulates
85 : // a chunk of visibility (typically all baselines for one time)
86 : // together with all the information needed for processing
87 : // (e.g. direction coordinates).
88 : //
89 : // Gridding and degridding in SDGrid are performed using a
90 : // novel sort-less algorithm. In this approach, the gridded plane is
91 : // divided into small patches, a cache of which is maintained in memory
92 : // using a general-purpose <linkto class=casacore::LatticeCache>LatticeCache</linkto> class. As the (time-sorted)
93 : // visibility data move around slowly in the image plane, patches are
94 : // swapped in and out as necessary. Thus, optimally, one would keep at
95 : // least one patch per scan line of data.
96 : //
97 : // A grid cache is defined on construction. If the gridded image plane is smaller
98 : // than this, it is kept entirely in memory and all gridding and
99 : // degridding is done entirely in memory. Otherwise a cache of tiles is
100 : // kept an paged in and out as necessary. Optimally the cache should be
101 : // big enough to hold all polarizations and frequencies for one
102 : // complete scan line.
103 : // The paging rate will then be small. As the cache size is
104 : // reduced below this critical value, paging increases. The algorithm will
105 : // work for only one patch but it will be very slow!
106 : //
107 : // The gridding and degridding steps are implemented in Fortran
108 : // for speed. In gridding, the visibilities are added onto the
109 : // grid points in the neighborhood using a weighting function.
110 : // In degridding, the value is derived by a weight summ of the
111 : // same points, using the same weighting function.
112 : // </synopsis>
113 : //
114 : // <example>
115 : // See the example for <linkto class=SkyModel>SkyModel</linkto>.
116 : // </example>
117 : //
