" ... the gravitational waves ... are consistent with the merger of 36 and 31 solar mass black holes at a distance of 1.3 billion light-years. The final, single black hole has 63 times the mass of the Sun, with the remaining 3 solar masses converted into energy in gravitational waves."
The two black holes have 36 and 31 solar masses, i.e. 67 solar masses in total. The resulting single black hole has 63 solar mass - so the difference is 4 solar masses. However, the text refers to "the remaining 3 solar masses". Am I missing something?
