Solar masses
In the recent news, it says "One black hole was about 36 times the mass of the Sun, and the other was about 29 solar masses. As they spiralled inexorably into one another, they merged into a single, more-massive gravitational sink in space-time that weighed 62 solar masses, the LIGO team estimates."--http://www.nature.com/news/einstein-s-gravitational-waves-found-at-last-1.19361?WT.mc_id=FBK_NatureNews
The math is wrong because 36+29=65. What happened to the unaccounted for 3 solar masses? Is there a mistake in the text here?

"Before crashing together, the black holes were 36 and 29 times the Sun's mass. Afterward, the new combined black hole has only 62 solar masses, with the colossal difference -- 5,000 supernovas' worth of energy -- radiated away as gravitational waves."

The waves came from black holes with 26 and 39 times the mass of the sun, respectively. Merged, the newly created black hole had 62 times the mass of the sun.
