J. Kissel I've gathered a full set of transfer functions to measure the IFO sensing and actuator functions. All looks quite normal, detailed analysis to come. The data lives here: Sensing Function Measurements 2017-04-27_H1DARM_OLGTF_4to1200Hz_25min.xml 2017-04-27_H1_PCAL2DARMTF_4to1200Hz_8min.xml 2017-04-27_H1_PCAL2DARMTF_BB_5to1000Hz_0p25BW_250avgs_5min.xml 2017-04-27_H1_OMCDCPDSUM_to_DARMIN1.xml <-- new measurement that captures the [mA/ct] scale of the digital portion of the sensing function Actuation Function Measurements UIM: 2017-04-27_H1SUSETMY_L1_iEXC2DARM_25min.xml 2017-04-27_H1SUSETMY_L1_PCAL2DARM_8min.xml PUM: 2017-04-27_H1SUSETMY_L2_iEXC2DARM_17min.xml 2017-04-27_H1SUSETMY_L2_PCAL2DARM_8min.xml TST: 2017-04-27_H1SUSETMY_L3_iEXC2DARM_8min.xml 2017-04-27_H1SUSETMY_L3_PCAL2DARM_8min.xml All has been committed to the Calibration SVN.
