\log_{10}{\rm DM_{\rm limit}} = \frac{1}{2.14}(-0.154 + \sqrt{0.0247 + 4.28(13.46+3.86\log_{10}{\nu}+\log_{10}{t_{\rm res}})}.  \end{equation}  Here $t_{\rm res}$ has units of seconds and $\nu$ has units of GHz.Figure \ref{fig:crossover_dm} shows the limiting DM for 200-ns and 1.6-$\mu$s timing resolution for SKA1\_Mid and SKA1\_Low bands, respectively.
