Figure \ref{fig:exgalSEDs} shows the spectra for the extra sources in the same format as fig. \ref{fig:starSEDs}, with the median SED highlighted in red. Overall, we see similar spectral behaviour between these two classes of sources, despite the different modelling approaches. This implies that they may be similar populations of sources (see sec. \ref{sec:extragalactic?}). Both classes of sources follow a roughly gaussian amplitude distribution at each frequency, showing no signs of a sharp cuttoff caused by our amplitude cut during the selection process. This is likely due to degeneracies between nearby sources in the model. Those with low amplitudes have had some of their emission sucked up by a nearby brighter source, possibly one within the same $0.11^{\mathrm{o}}$ pixel. About \emph{GET A NUMBER HERE}\% of sources end up with amplitudes consistent with 0, and are not shown in these plots and so in a subsequent analysis these sources could be trimmed from the model to save computational time and reduce its complexity.
Figure \ref{fig:exgalSEDs} shows the spectra for the extra sources in the same format as fig. \ref{fig:starSEDs}, with the median SED highlighted in red. Overall, we see similar spectral behaviour between these two classes of sources, despite the different modelling approaches. This implies that they may be similar populations of sources (see sec. \ref{sec:extragalactic?}). The extra sources are on average brighter, due to the larger magnitude cuttoff when selecting these sources (dimmer ones were incorporated into the diffuse template). Both classes of sources follow a roughly gaussian amplitude distribution at each frequency, showing no signs of a sharp cuttoff caused by our amplitude cut during the selection process. This is likely due to degeneracies between nearby sources in the model. Those with low amplitudes have had some of their emission sucked up by a nearby brighter source, possibly one within the same $0.11^{\mathrm{o}}$ pixel. About 46\% of sources end up with amplitudes consistent with 0, and are not shown in these plots and so in a subsequent analysis these sources could be trimmed from the model to save computational time and reduce its complexity.

\caption{Description of 20 extragalactic sources, the 10 brightest and 10 randomly selected ones. The bright sources are almost entirely found within the boundaries of other very bright sources in the optical (denoted with type *), so their brightnesses may be influenced by this confusion. Those with types listed as a dash have no catalogue information about their classifications.}
