| Image based deconvolver
| |
| | |
| Several algorithms are available to deconvolve an image with a
| |
| known psf (dirty beam), or a Gaussian beam. The algorithms
| |
| available are clark and hogbom clean, a multiscale clean and a
| |
| mem clean. For more deconvolution control, use clean.
| |
| | |
| Keyword arguments:
| |
| imagename -- Name of input image to be deconvolved
| |
| model -- Name of output image containing the clean components
| |
| psf -- Name of psf image (dirty beam) to use
| |
| example: psf='casaxmlf.image' .
| |
| If the psf has 3 parameter, then a Gaussian
| |
| psf is assumed with the values representing
| |
| the major , minor and position angle values
| |
| e.g psf=['3arcsec', '2.5arcsec', '10deg']
| |
| alg -- algorithm to use: default = 'clark'
| |
| options: clark, hogbom, multiscale or mem.
| |
| niter -- Maximum number of iterations
| |
| gain -- CLEAN gain parameter; fraction to remove from peak
| |
| threshold -- Halt deconvolution if the maximum residual image is
| |
| below this threshold.
| |
| default = '0.0Jy'
| |
| mask -- mask image (same shape as image and psf) to limit region
| |
| where deconvoltion is to occur
| |
| | |
| ------parameters useful for multiscale only
| |
| scales -- in pixel numbers; the size of component to deconvolve.
| |
| default value [0,3,10]
| |
| recommended sizes are 0 (point), 3 (points per clean beam), and
| |
| 10 (about a factor of three lower resolution)
| |
| ------parameters useful for mem only
| |
| sigma -- Estimated noise for image
| |
| targetflux -- Target total flux in image
| |
| prior -- Prior image to guide mem
