Detailed Description

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

Intended use:

Public interface

Prerequisite

Etymology

MSCleanImageSkyModel implements the MS Clean algorithm. It is derived from SkyModel .

Synopsis

The MS Clean is the Multi-Scale clean, collecting flux in several different scale size Gaussian components. It is highly effective in imaging extended structure and results in residuals with excellent statistics.

The MS Clean is implemented using the LatticeCleaner class.

Masking is optionally performed using a mask image: only points where the mask is non-zero are searched for Gaussian components. This can cause some difficulty, as the different Gaussian scale sizes will extend beyond the mask by different amounts. If no mask is specified all points in the inner quarter of the image are cleaned.

Example

See the example for SkyModel .

casa::MSCleanImageSkyModel::MSCleanImageSkyModel	(	const Int	nscales,
		const Int	stoplargenegatives = `2`,
		const Int	stoppointmode = `-1`,
		const Float	smallScaleBias = `0.6`
	)

Create a MSCleanImageSkyModel with nScales, we figure out what they are.

casa::MSCleanImageSkyModel::MSCleanImageSkyModel	(	const Vector< Float > &	useScaleSize,
		const Int	stoplargenegatives = `2`,
		const Int	stoppointmode = `-1`,
		const Float	smallScaleBias = `0.6`
	)

Create a MSCleanImageSkyModel, you provide the scale sizes, IN PIXELS for example: Vector<Float> scales(4); scales(0) = 0.0; scales(1) = 3.0; scales(2) = 10.0; scales(3) = 30.0;.
