we wait for a second round (1000 to 8 Hz) 
because the first round was polluted by some scattered light (triggered by Maria's movements)
and the excitation of
some structures around 34.5 Hz and 36-38 Hz 
13:09:11

seems that thre are structures in hrec around 34.5 and 36-38 which breath ....
NO: they are calib lines, no such excitation is seen in LSC_DARM, or hrec_raw.

16:34:59 start agian, good one, and LAST ONE!!!!
16:40:36

looking at the CURR_MON we observe that beside
the line, we are also injection some broadband noise 
this broadband noise grows in amplitude when the line aproaches 1000 Hz

Another think we notice is that AFTER we have stopped the injection
the ACL restarts from the f_start and injects a few seconds of a new sweep.

We bring the setup in EE room
