we use No.5 signal with mass ratio q = 8.
We use No.5 signal with mass ratio q = 8, M=150, d=5.
As we can see, the posteriors are similar.
Fig.1 No.5 signal with mass ratio q = 8, random seed = 100.

## (2) Bilby
### (i) No.5 signal
We use spinning BBH template to do PE run on No.5 signal with mass ratio q = 8. Fig.4 and Fig.5 have totally the same parameters and noise, just to verify the stability of Bilby's results. To my surprise, it changes a lot.

### (ii) No.2 signal
We also use spinning BBH template to do PE run on No.2 signal with mass ratio q = 1.
We also use spinning BBH template to do PE run on No.2 signal with mass ratio q = 1, M=150, d=15.
As we can see, the posteriors are similar, while there is a little difference. The distance isn't estimated accurately.

# 2. BBH
## (1) Bilby
First, we produce a high mass BBH signal. m1=89, m2=60, distance=3000, to see how it performs with different noises in Bilby.
As we can see, the posteriors are similar, while there is a little difference. The distance isn't estimated accurately. Fig.4 and Fig.5 have totally the same parameters and noise, just to verify the stability of Bilby's results.
