The frequency dependence of the S/N for GBT, VLA, SKA-MID and full SKA searches for MSPs at the Galactic Center. The filled and open symbols are, respectively, for the weak-scattering (i.e., magnetar-like) and strong-scattering scenarios. The symbols plotted are for MSPs with the listed periods (1, 5, and 20 ms), a duty cycle of 10% and a spectral index of −1.7. The vertical axis gives the expected S/N after a 30 hr integration for an MSP with a 1.4 GHz luminosity of ﹩{{L}_{1.4}}=10\;﹩ mJy kpc². The frequency ranges of the current suite of available receivers for each telescope is shown at the top of each panel. The optimal frequency band for MSPs with periods ≲10 ms is 8–12 GHz in the weak-scattering case, and 18–26 GHz (i.e., K-band) in the strong-scattering case.
