Detailed Description

An FTMachine for Gridding Single Dish data.

Intended use:

Public interface

Prerequisite

FTMachine module
SkyEquation module
VisBuffer module

Etymology

FTMachine is a Machine for Fourier Transforms. GridBoth does Single Dish gridding in a similar way

Synopsis

The SkyEquation needs to be able to perform Fourier transforms on visibility data and to grid single dish data. GridBoth allows efficient Single Dish processing using a VisBuffer which encapsulates a chunk of visibility (typically all baselines for one time) together with all the information needed for processing (e.g. direction coordinates).

Gridding and degridding in GridBoth are performed using a novel sort-less algorithm. In this approach, the gridded plane is divided into small patches, a cache of which is maintained in memory using a general-purpose LatticeCache class. As the (time-sorted) visibility data move around slowly in the image plane, patches are swapped in and out as necessary. Thus, optimally, one would keep at least one patch per scan line of data.

A grid cache is defined on construction. If the gridded image plane is smaller than this, it is kept entirely in memory and all gridding and degridding is done entirely in memory. Otherwise a cache of tiles is kept an paged in and out as necessary. Optimally the cache should be big enough to hold all polarizations and frequencies for one complete scan line. The paging rate will then be small. As the cache size is reduced below this critical value, paging increases. The algorithm will work for only one patch but it will be very slow!

The gridding and degridding steps are implemented in Fortran for speed. In gridding, the visibilities are added onto the grid points in the neighborhood using a weighting function. In degridding, the value is derived by a weight summ of the same points, using the same weighting function.

Example

See the example for SkyModel.

Motivation

Define an interface to allow efficient processing of chunks of visibility data

Constructor: cachesize is the size of the cache in words (e.g.

a few million is a good number), tilesize is the size of the tile used in gridding (cannot be less than 12, 16 works in most cases), and convType is the type of gridding used (SF is prolate spheriodal wavefunction, and BOX is plain box-car summation). mLocation is the position to be used in some phase rotations. If mTangent is specified then the uvw rotation is done for that location iso the image center.
