Make a clean image using the Clark Clean a threshold

Synopsis
clarkclean(niter, gain, threshold, displayprogress, model, mask, histbins, psfpatchsize, maxextpsf, speedup, maxnumpix, maxnummajcycles, maxnummineriter)

Description

In the Clark Clean algorithm, the cleaning is split into minor and major cycles. In the minor cycles only the brightest points are cleaned, using a subset of the point spread function. In the major cycle, the points thus found are subtracted correctly by using an FFT-based convolution.

Arguments

niter		Number of iterations
		Allowed:	Int
		Default:	1000
gain		Loop Gain for CLEANing
		Allowed:	Double
		Default:	0.1
threshold		Flux level at which to stop CLEANing
		Allowed:	Quantity
		Default:	'0Jy'
displayprogress		Display the progress of the cleaning?
		Allowed:	Bool
		Default:	F
model		Name of images
		Allowed:	String
mask		Name of mask images used for CLEANing
		Allowed:	String
histbins		Number of bins in the pixel-flux histogram
		Allowed:	Int
		Default:	500
psfpatchsize		Size of PSF for minor cycle
		Allowed:	Vector of Int
		Default:	[51,51]
maxextpsf		maximum external sidelobe, used to set depth of minor cycle clean
		Allowed:	Double
		Default:	0.2
speedup		Cleaning speedup exponent
		Allowed:	Int
		Default:	0
maxnumpix		Maximum number of pixels used in each minor cycle
		Allowed:	Int
		Default:	10000
maxnummajcycles		Max number of major cycles; -1 = no restrictions
		Allowed:	Int
		Default:	-1
maxnummineriter		Max number of minor iterations; -1 = no restrictions
		Allowed:	Int
		Default:	-1

Returns
Bool
