... User Guide ] Task: clean Purpose: Apply Hogbom, Clark or Steer CLEAN algorithm to a map Categories: deconvolution CLEAN is a MIRIAD task that performs a hybrid Hogbom/Clark/Steer Clean algorithm, which takes a dirty map and beam, and produces an output map which consists of the Clean components. This output can be input to SELFCAL to self-calibrate visibilities, or input to RESTOR to produce a "clean" image. ... Key: map The input dirty map, which should have units of Jy/beam. No default. ...

... Previous: ESO C Library for an Image Processing Software Environment (eclipse) . ... A new CLEAN-type algorithm searches for model components not in the dirty image but in the multi-resolution wavelet transform of the dirty image based on the dirty beam. ... The improvement of this prototype Wavelet CLEAN, which does convolve with the dirty beam, can be attributed to a suppression of noise and aliasing in the dirty image by use of information in the sidelobes of the whole image domain. ...

... In this example, with Mizar consisting of two identical components, we can just apply the classic CLEAN deconvolution algorithm in conjunction with a phase self-calibration step ("hybrid mapping") to the combined data of all NPOI channels. ... It is a clickable map for explanations of the maps and buttons. ... If we grab the slider, after a brief delay it will be movable and we can study the changing residual and final maps as a function of the number of CLEAN components subtracted. ...
