Comment to MICH/PRCL subtraction in h(t) is not optimal (46518)

Following these entries, I have restarted HrecClean at 14h50 UTC with a different noise subtraction configuration than Hrec: frequency separation between SPRB_B4_56MHz_Q and 1:SIB2_B2_8MHz_I moved from 90 Hz to  150 Hz ; maximum frequency of V1:SDB2_B1s1_PD1_Blended increased from 1 kHz to 2 kHz ; notches around 19.1 Hz removed from the subtraction of V1:SNEB_B7_DC and V1:SWEB_B8_DC. At first glance, the range is improved by ~0.5 Mpc.

HRecClean, HrecPD1 and HrecPD2  were restarted with an updated version v3r09p1 instead of V3r09) allowing the process to reach the Golden state (and the process to be green in VPM). HRec process will be restarted with this new version when the ITF will be unlocked during the on-going calibration period.

The configuration of the main HRec process will be updated in the coming days after tuning of the noise subtraction parameters.
