Differences in definitions of SNR

Using git_hash = bc899386, we noticed on the bilby review some differences in the SNR "angle" quantities, e.g.

Since the Bayes factors, and other posterior values which are sampled in agree between bilby and LALInference, our feeling was that this is likely a definition issue, but I'm not 100% sure. For reference, the full summary page can be viewed here:
