Description

Etymology

MFCEMemImageSkyModel implements the MF Clean algorithm. It is derived from SkyModel.

Synopsis

Rewrite me for MEM! The MF 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.

The MF Clean is implemented using the class.

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.
