It identifies in the dirty map CLEAN components and convolve them with a deduced synthetic beam. Different CLEANing methods can be used. HOGBOM and CLARK are recommended for being the most robust (see MAPPING manual for details). By using SUPPORTs the search for CLEAN components can be restricted to the areas where the source is known to be (when the variable myclean%support=yes, see Sect. ). The criterion to stop the search for CLEAN components within the residual map can be modified by changing the Stopping criteria options in the CLEAN parameters widget (Fig. ). By default no supports are used in a first CLEANing of a dirty map, but can be defined for later CLEANing. The option to CLEAN with supports can also be set on or off in the CLEAN parameters widget. By default the flux accumulated in the identified CLEAN components is shown (if myclean%show=yes), and stored in a file of name including -cct.
HOGBOM/CLARK/others at the top of the imaging widget permits CLEANing by using the defined parameters.
RESIDUALS/CLEAN/CCT at the top of the imaging widget plots the resulting residuals (stored in a file of extension .lmv-res), the CLEANed image (in a file of extension .lmv-clean) or the found CLEAN components (in a file of extension .lmv-cct).
