Glossary : Range / sensitive volume

• For 'range', why 'at cosmologically significant distances' and what does that mean quantitatively? Doesn't range have the same definition and meaning at all distance scales? Maybe the thinking here is 'we are implicitly considering a source population which is approximately uniform through spatial volume', which only makes sense (the implicit assumption of uniformity) on scales much larger than a single galaxy? So, maybe better to write 'given source population distributed over distance scales much larger than a galaxy' or similar?

• For 'sensitive volume', the idea of 'the limit of detection' is not defined or explained. For a proper definition of range etc we would need a quantitative measure. That presumably would imply saying the SNR for a single detector is set to 8, etc., as that is what we actually use. Of course this is a notional limit of detection which does not correspond to our actual detection methods. Even if we do not state any particular number here, it would be a significant improvement to simply explain 'limit of detection' by saying it means a fixed single-detector or network SNR threshold.
