Checked coherences with LSC and ASC loops

Sheila, Jennie W

 

While Sheila runs a Bruco I checked the coherence from LSC - SRCL, PRCL, MICH,  and ASC-MICH, DHARD and CHARD to DARM.

The first image is from our lock last night, the second is the same set of measurements from Monday night when we had a range of 156 MPc (left cursor).

Comparing the two it looks like PRCL coherence is slightly worse since Monday, CHARD looks about the same, DHARD is slightly worse in pitch but better in yaw, ASC-MICH is about the same, PRCL is a bit worse, SRCL is about the same and LSC-MICH is a bit worse.
