 \emph{s\_resolution\_best, s\_resolution\_worse} are estimated like the typical value (see subsection \ref{sec:res}) where $\lambda$ is replaced respectively by the minimum and maximum wavelength of the spectral range(s). The size D is the telescope diameter for SD observations and the largest distance in the \emph{uv} plane for interferometry. Beam forming may represent an exception to this rule, see \ref{sec:res}.

 wavelength (and again typical value SHOULD be estimated as the mid value of the spectral range apart from documented exceptions) and l is the typical smallest distance in the \emph{uv} plane. This parameter is not relevant for other observation modes.
-The maximum angular scale is also variable along the spectral range. That's why we bound it with \emph{s\_maximum\_angular\_scale\_min} and \emph{s\_maximum\_angular\_scale\_max} estimated as  respectively $\lambda\_min/l$ and  $\lambda\_max/l$
