I've grabbed the full calibration suite today, since (a) we'll take as much data on the sensing function as we cal get, and (b) it's been two weeks since the last actuator measurement set, and (c) This will be a good reference set if we enact ECR E1900049, which we'll have to pull the PUM drivers, replace an hopefully-unrelated-to-the-main-path noise monitor board, and then re-install. We may enact this ECR tomorrow, if we can past the tumbleweeds to get to EX. 

Processed data will be included in future analysis to be posted later.

Total calibration time used: 1.5 hours.

IFO was in the now nominal configuration:
    - 38.0W in to the IMC, with the IFO thermalized for a few hours prior to start of data taking
    - 50 ct digital offset in SRCL
    - UIM driver state = 1 (no switchable analog low passes engaged)
    - PUM driver state = 3 (switchable analog low passes engaged), 
    - ESD driver state = 2 (switchable analog low passes engaged)
    - L2 OSEM to R0 TOP Coils feedback to maintain distance between reaction chain and test mass chain is now ON.
