\section{Science use cases and translation to ADQL queries based on ObsCore Radio extension }
\label{ADQLusecases}

\subsection{Science case }

\textit{ The queries in subsections \ref{sec:s_resolution_max} and \ref{sec:s_fov_min}
can be run with s\_resolution\_min and s\_fov\_max instead of s\_resolution\_max and
s\_fov\_min respectively, to obtain results in which at least part of the dataset satisfy the condition.\\
For instance, consider datasets with a large observed bandwidth, like those taken with wide/ultrawide band receivers.
The condition s\_resolution\_max<d\_typical may not be satisfied. At the same time, the user may want to select those
dataset where the desired condition on spatial resolution is matched at least partially within the observed band.}
