Package general
Module deconvolver
Tool deconvolver


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
