\usepackage{mathtools}  \section{Overview}  This document presents a parametric model to help design an Interferometric Array. It describes the relationship of design parameters in section 2 with performance objectives in section 3.   In particular, this document focus in providing provides  a quick guide to understand an explanation of  the parameter parameters  and objectives selection for selection. These explanations enable  the reader to both assess completeness of the model, and accuracy of the mathematical relationships as well. Section 4 provides the python code used to generate a table data  in the format required to perform a for  visual analysis of the performance of different arrays generated by the model. array design options performance.  The python code is consistent with parameters and objectives selection, selection in sections 2 and 3,  and the mathematical relationships between them. \section{Design Variables}  This section aims to include all relevant design parameters that might influence the selected performance objectives.  \subsection{Antenna Aspects}
