Hi all,

Could you guys please point me to the reference where I can see how units are defined for a binary black hole simulation?

(Or possibly simply answer):

I just want to know what the units of space and time (M) are.

What is M? is it the ADM mass at initial time? the addition of the two black hole masses?... or so...

I apologize in advance in case my question is terribly dummy. 

Thanks,

Francisco
