- 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.
