==== Report of work ====
 * COM: Finesse of Yarm was ~1200 with 60K of ITMY that is a bit lower than expected value even it was estimated by 10% lower ITM reflectivity.
 * CRY: Temperature of ITMY will go lower from above results to distinguish ITMY contamination effect.
 * CRY: Cooler for shield for all 4 test mass, and cooler for payload for ITMY and ITMX and ETMX are working. 

==== Work plan ====
 * Type B: Needs tuning for BS SR3.
 * Type A: RT model was separated to two parts for ETMX and ITMX. It needs more time today. dackill should be implemented in both model.
 * Off loaded FS for BS.
