I took a set of our regularly scheduled measurements of the DARM sensing function to add to our O2 data set. Processed results to come. The data lives here: 
    /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Measurements/SensingFunctionTFs/
        2017-07-19_H1_OMCDCPDSUM_to_DARMIN1.xml                          == C, covering conversion from mA of DCPD sum to DARM_IN1 [ct].
        2017-07-19_H1DARM_OLGTF_4to1200Hz_25min.xml                      == 1 / (1 + G)
        2017-07-19_H1_PCAL2DARMTF_4to1200Hz_8min.xml                     == C / (1 + G)
        2017-07-19_H1_PCAL2DARMTF_BB_5to1000Hz_0p25BW_250avgs_5min.xml   == broad band excitation to compare PCAL against calibrated Detector Output 

As before, we should use TX PD as reference, since it's been confirmed that PCALY's RX PD is continuing to suffer from clipping (e.g. LHO aLOG 37409)
