+Typical values of the parameters s\_fov and s\_resolution  are estimated assuming the typical value of the spectral range which can be considered as (em\_max - em\_min)/2
 \emph{s\_fov\_min, s\_fov\_max} are estimated like the typical value (see subsection \ref{sec:fov}). 
 In the case of SD pointed observations with mono-feed receivers and the majority of interferometric observations the minimum and maximum
 $\lambda$ values in the spectral range(s) will be used in the formula. In the case of mapping scans or multi-feed/PAF receivers
