Hello,  
I want to compare the gravitational wave signal before the merger ( a model ) and the observed signal energy as the CBC merged and the radiated energy. Can you suggest me models and calculations about the GW energy?

@Raghad Thank you for your question! I think there is a good discussion of GW radiated energy in the “Physics of GW150914 paper”, linked below. In general, we try to fit models to the data, and then can calculate the radiated energy from a given model.
