+Further to the review above, we extend the bilby review to include
+
+### Summary
+1. A full calibration review in which posterior calibration samples where compared for GW150914. This revealed minor differences between the handling of calibration between LI and Bilby which have been resolved
+2. An extension of the spin limits to the maximum values possible for each prior: reruns of the PP tests demonstrate the sampler remains unbiased
