  • there are no oplev signals in MC1, MC2, and MC3

 None of the 3 MC optics have oplevs, so there shouldn't be any oplev signals. Although MC2 has the trans QPD, which was once (still is??) going through the MC2 oplev signal path.

.......

 

The MC2 Oplev signal path has been modified in the c1mcs model.  The ADC channels have been sent over the rfm into c1ioo model and are currently used in the WFS servo loops.  Please see this elog 5397.
