Important Remarks

• The more a priori information we introduce, the more the problem is constrained. Although it is not presented in this section, the user can impose a support contraint on the solution via the POLYGON procedure. This could be particularily important for Clean, but not that much for WIPE since it has its own strategy to define the support.
• One point to stress here is the importance of the regularization step. Since it is the one which sets the objectives to reach in spatial frequency resolution. The size of the Neat Beam is only a consequence of the previous choice. The parameter that controls the spatial frequency resolution is APERTURE[2]: the multiplicative factor for the major and minor axis of the ellipse corresponding to the aperture to synthesize.
