Detailed Description

Clark Image Sky Model: Image Sky Model implementing the Clark Clean algorithm.

Intended use:

Public interface

Prerequisite

ImageSkyModel module
ClarkCleanImageSkyModel module

Etymology

PClarkCleanImageSkyModel implements the Clark Clean algorithm. It is derived from SkyModel .

Synopsis

The Clark Clean is an FFT-based clean algorithm. Cleaning is split into major and minor cycles. In a minor cycle, the brightest pixels are cleaned using only the strongest sidelobes (and main lobe) of the PSF. In the major cycle, a fully correct subtraction of the PSF is done for all points accumulated in the minor cycle using an FFT-based convolution for speed.

Masking is optionally performed using a mask image: only points where the mask is non-zero are cleaned. If no mask is specified all points in the inner quarter of the image are cleaned.

Example

See the example for SkyModel .
