The Alpha filter for the MICH subtraction from DARM has been improved, in order to reflect any changes happened after the interventions in the SDB1 and the PR towers. As usual, there is no direct effect on the sensitivity but only on the loops: the residual coherence is sufficiently lower (Figure 1), the suppression is improved w.r.t before (Figure 2) and the MICH contribution to the longitudinal Noise Budget is now sufficiently low, with only some margin left around 15 Hz (Figure 3).
