Cal Team Day 2 Debriefing

Lots more work done today -- still a fire hose of measurements that we're furiously trying to understand quickly enough to make a statement about them and/or use them in our loop models, but we're falling behind the analyzing / documenting as expected.

What we accomplished today:
J. Kissel, S. Karki
Finished measurements of ETMX PCAL electronics, as had been done for ETMY yesterday (AA and AI data finished being processed, still need to process full-chain measurements; both end station's work need aLOGs)

K. Izumi, J. Kissel
Gathered Free-Swinging Michelson calibration of ETMY L2 stage between 2 and 7 [Hz] (by the usual daisy chain of measurements), tried to get L3 stage but it's just too weak -- will have to do an ETMX to ETMY propogation using the full IFO. (measurement processed, needs aLOG for procedure and results)

K. Izumi
Gathered data for calibration of ETMY L2 stage using ALS DIFF VCO (preliminary aLOG is LHO aLOG 18656, but still needs process and results aLOG)

R. Savage, D. Tuyenbayev
Compared response of standard ETMY PCAL PDs against other broadband PDs to check for high-frequency frequency dependence. Still needs more time (and an aLOG).

R. Savage, D. Tuyenbayev, J. Kissel
Begun looking at changes to be made to CAL-CS model and PCAL models. Accidentally updated ${userapps}/cal/common/models/ and found new library parts which need new connections and IPC at the top level that we don't know the details about.

Goals for tomorrow:
B. Weaver
Measure ETM charge

R. Savage, D. Tuyenbayev
Continue at EY, and move to EX comparing high frequency response of PDs.

J. Kissel, K. Izumi
Measure Simple Michelson Technique again, but propagate to stronger ETMX this time (and get all three stages), then lock of DARM to propagate from ETMX to ETMY (again all three stages)

J. Kissel, R. Savage, D. Tuyenbayev
Call up J. Betzwieser and S. Kandashamy and figure out what the heck they've done to the CAL-CS and PCAL library parts, so that we can absorb the changes and have functional front end models.
