deconvolve performs minor cycle deconvolution directly on a dirty image. No MS is required. 

 

Parameter descriptions

imagename

The input dirty image that will be deconvolved.

model

The output cleaned image containing a deconvolved point model.

psf

Can be either be an image (e.g., a psf that tclean has calculated), or a list of values that define a Gaussian, e.g., psf=['3arcsec', '2.5arcsec', '10deg'] defines a Gaussian with '3arcsec' as the major axis, '2.5arcsec' as the minor axis, and a position angle of 10 degrees. 

alg

The clean algorithm to use by deconvolve. Several algorithms are available to deconvolve an image with a known psf (dirty beam), or a Gaussian beam. The algorithms are 'clark' (default) and 'hogbom' clean, 'multiscale' clean and a Maximum Entropy 'mem' clean. Details on the algorithms are given in the Synthesis Imaging chapter in the page describing Deconvolution Algorithms.

alg='multiscale' expandable parameters

scales

A list of scales in units of pixels (see the deconvolve examples tab).

alg='mem' expandable parameters

sigma

This parameter allows the user to input an expected noise value, which will allow for a faster convergence.

targetflux

The estimated total flux in the image.

prior

A starting model to be used by deconvolve. If no prior is provided, a flat image will be used.

 

niter

The number of iterations to perform on the image. Default: 10

gain

Sets the CLEAN gain parameter. Default: 0.1

threshold

Sets the lower level below which sources will not be deconvolved.

mask

The image mask to limit the region of deconvolution.
