Since some time we had connected 4 phase shifters in series for the CLF demodulator (CLF_REFL_RF6, OMC_TRANS_RF3, HD_DIFF_RF3 and SPARE_D_RF) and none in the OMC and homodyne paths. This update consolidates the 4 delay phase shifters into a single CLF_REFL_RF6 unit that has 4 times the range. The slow controls channels for the HD_DIFF_RF3 and SPARE_D_RF units are gone.
