            <p>
                Source templates are normalized using Gaia G-band flux relative
                to the science target. A relative flux of 1 identifies the
                reference normalization used for the target spectrum. Only
                sources retained by the instrument simulation as potential
                contaminants at one or more evaluated position angles are shown.
