I have some questions about the first discovery paper that was released about gravitational waves, especially some of the maths.(adsbygoogle = window.adsbygoogle || []).push({});

How did they:

1. Calculate the masses of the black holes that merged

2. Calculate the energy radiated away in gravitational waves

3. Calculate how far away the event happened

(I assume the third can be calculated with a formula that involves amplitude, but I am yet to find the right formula's for any of these)

Sorry if this is easily solvible but I couldn't find the answers myself.
