I've completed an entire suite of calibration measurements this morning, which contains the first actuator assessment after the May 2017 vent. Preliminary screen shots attached, and svn file locations listed below.

Actuation Function Characterization

        2017-06-14_H1_PCAL2DARMTF_BB_5to1000Hz_0p25BW_250avgs_5min.xml == broad band excitation to compare PCAL against calibrated Detector Output


Analysis to come. Note that we should likely use (export) H1 PCALY's TX PD (as opposed to RX PD) as our displacement reference such that we're not confused by the RX PD's recently identified temperature sensitivity (see LHO aLOG 36884).
