No, we don't want low Q for the PMC RFPDs. We want Q ~10 for the RefCav RFPDs, and whatever high Q we can get for the PMCs, so that the SNR can be high with low light. The PMCs should have a low modulation index, so the more SNR, the better. But the PMC RFPD noise requirement is not stringent, so don't spend more than a day on these.
