 mass_1 is estimated a bit lower than real value.   
 distance is much higher.   
+## (7)VItamin: bilby test  
+This step is to test VItamin with BBH waveform generated by bilby.   
+The injection parameters are all set as median value of prior's range:

+The posterior doesn't look good, especially theta_jn.    
+What's the problem, is it an error from waveform's amplitude ? Because we can see that this nosiy data's amplitude (in L1) is 10^-22, the whitened one is 10^1.
