In Table \ref{tab:bands} we define 6 observing bands based on the SKA1\_Mid and SKA1\_Low bands available post rebaselining.   \begin{table}   \centering  \label{tab:bands}   \caption{The post-rebaselining observing bands of SKA1\_MID}   \begin{tabular}{ l r r}   \hline  Band/Configuration & $\nu_{\rm min}$ (MHz) & $\nu_{\rm max}$ (MHz)\\  \hline  Mid band 1 & 350 & 1050 \\   Mid band 2 & 950 & 1760 \\   Mid band 5 & 4600 & 13,800 \\   Low configuration 1 & 250 & 350 \\  Low configuration 2 & 150 & 350 \\  Low configuration 3 & 50 & 350 \\  \hline  \end{tabular}   \end{table}  \\ Figure \ref{fig:scattering_timescales} shows the best-case scattering broadening as a function of DM for lowest frequency a range  of each band/configuration (i.e. the frequency at which scattering will have the largest effect). SKA1 observing frequencies.  The point at which the scattering timescale exceeds the timescale implied by new versions of SKA1-SYS\_REQ-2961 and SKA1-SYS\_REQ-2962 (see above) ultimately determines the maximum DM that must be supported by the SKA PST.
