Subject: Comparison bewteen beat from PLL and FC 

I used PLL feedback to measure beat noise from dc to 3 Hz and dc to 1.5 Hz to compare with the data taken yesterday by FC.

 

There is no peak around 3 Hz (probably a peak from cavity suspension)in FC data, I'm not quite sure if we what we see is real or not.
