Not an astrophysicist so it might be a stupid question. If the combined mass of the pair is calculated to be well outside the range of what we find in our galaxy, could it be that it is not the mass but some other inputs to the calculation? From what I understand there is still a challenge to determine distances to the very far objects (that is one of the reasons for recent news about “Hubble not so constant”)

It uses the fact that we can estimate the masses[2] based on the change in frequency of the chirp signal.
