HAM3 (MC2, PR2) close out Transfer function measurements looks Healthy

Both MC2 and PR2 suspensions in HAM3 chamber are healthy as per the transfer function measurements I took this morning. Please see the plots attached below, the templates are stored at the following location,

MC2 T_dof (see page 4) has a small unwanted peak at around 4.1Hz which I suspect is due to the purge air in the Chamber. However it looks better when I took a second measurement as shown here. So nothing to worry.
