Detailed Description

defines interface for the Fourier Transform Machine

Intended use:

Public interface

Prerequisite

Etymology

FTMachine is a Machine for Fourier Transforms

Synopsis

The SkyEquation needs to be able to perform Fourier transforms on visibility data. FTMachine allows efficient Fourier Transform 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. UVW coordinates).

Example

A simple example of a FTMachine is found in GridFT . See the example for SkyModel .

Motivation

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

Note that the image must be Complex. It must contain the Complex Stokes values (e.g. RR,RL,LR,LL). FTMachine uses the image coordinate system to determine mappings between the polarization and frequency values in the PagedImage and in the VisBuffer.
