Vicky and I plugged in the 785 to the IMC common mode board.   The first attachment was taken while Oli was trying to lock DRMI, with 10W into the IMC for CHECK_MICH_FRINGES, ugf just over 4kHz.  The second attachment was taken at full lock, nominal low noise, a nearly 80kHz UGF.  This is somewhat higher than in March 76753
