Basically, we can see that:
mass_1 is estimated a bit lower than real value.
distance is much higher.
## (7)VItamin: bilby test
## (7)VItamin: bilby BBH waveform 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:

Waveform is injected in 3 detectors(L1, H1 and V1), here we plot the one in L1:

Then whiten it:

Input the waveform (in 3 detectors) to VItamin, and we get an estimation:

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.
What's the problem, is it an error from waveform's amplitude ? Is it at the right order of magnitude(10^-22)?
