This morning I took transfer function measurements on all of the suspensions in HAM6 chamber and they look healthy.
The templates are given below,

The postprocessing of the data is still ongoing and the plots will be posted soon.
I commited all the data to the svn and processed the results.
OM1:
Looks good.
OM2:
All the plots look frequency shifted a Hz smaller except for in L.
OM3:
Looks good.
OMC:
Some peaks shifted to the right/larger frequency by <1Hz or so.
The current measurements taken on OM2 is consistent with previous results (see LHO alog 65028) and so its all good.
OMC is also healthy and consistent with previous measurements taken in the past 1 year - see plot attached below.
