Detailed Description

SimpComponentFTMachine: does the simplest Fourier transform on SkyComponents.

Intended use:

Public interface



ComponentFTMachine is a Machine for Fourier Transforms of SkyComponents


Does a simple transform of a sky component. The phase term is fully accurate but no smearing is included.



Allow transformation of sky components.
