By re-writing $t_{\rm res}$ in equation \ref{eqn:limiting_dm} in terms of spin period ($P_0$) and number of bins across the pulse profile ($n_{\rm bins}$), we can use equation \ref{eqn:limiting_dm} to now determine the maximum DM that must be supported for pulsar timing (specifically using coherent dedispersion) with SKA1: SKA:    \begin{equation}  \label{eqn:limiting_dm_p}  t_{\rm res}(P_0) = \max \left(200\ {\rm ns}, \left(t_{\rm min},  \frac{P_0}{\min (n_{\rm bins},2048)} \right). \end{equation}  Here shorter periods mean larger computational and memory costs, but also lower maximum DMs due to the effect of scattering. As we move to higher periods, Here, $t_{\rm min}$ is  the computational minimum effective time resolution as described by requirements 2961  and memory cost drop significantly 2962 (200~ns  and the maximum DM rises. 1.6~$\mu$s for SKA1\_Mid and SKA1\_Low, respectively).
