binary pulsars as detectors

Mike Kesden (NYU) and I spent an enjoyable two hours coming to final consensus on what we think of the Hui et al paper about GW detection. We built an order-of-magnitude argument from the ground up (which confirms the Hui results but which, sadly, doesn't exist in the Hui paper). In the end, we reproduce the Hui expressions but do not confirm their final numbers. The paper is vague about how they get their final numbers, but I think the discrepancy must be in the bandwidth; I think the Hui team is mis-estimating the bandpass in which the effect is relevant.
