\label{eqn:best_case_scattering}  \log_{10} \tau_{s_{\rm best}}(\nu,{\rm DM}) = \log_{10} \tau_s(\nu,{\rm DM}) - 4.  \end{equation}  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 for which the SKA1 pulsar timing instrumentation must support phase-coherent dispersion removal. Beyond this DM, the computational cost of coherent dedispersion can be decreased by trading time resolution for frequency resolution.
