J. Kissel, T. Shaffer, J. Driggers Joe Betz and Jenne Driggers spoke of increasing the calibration line heights that drive the ETMX actuation stages in the face of the elevated noise in the detector in the 10-20 Hz frequency region (LHO:77993). TJ caught me, pointed this out to me, so I've staged this change by editing - /opt/rtcds/userapps/release/isc/h1/guardian/lscparams.py (rev 27751 lines 481 - 484) here, I increased the gains on the calibration line oscillators STAGE FROM TO FACTOR OF UIM / L1 6.6 15.0 ~2x PUM / L2 1.7 8.0 ~4x TST / L3 0.061 0.1 ~2x - /opt/rtcds/userapps/release/isc/h1/guardian/ISC_LOCK.py (rev 27729, lots of lines, where "CAL_LINE" appears in several states) here, as indicated in Louis' aLOGs where he's changed the line heights (e.g. LHO:71947), one *also* needs to change the correspond gains in the front-end calibration pipeline's demodulation of the lines. So I've added the following lines to the existing for loop that changes these gains for g in ['CLK','SIN','COS']: ezca['CAL-CS_TDEP_SUS_LINE1_COMPARISON_OSC_%sGAIN'%(g)] = (value) ezca['CAL-CS_TDEP_SUS_LINE2_COMPARISON_OSC_%sGAIN'%(g)] = (value) ezca['CAL-CS_TDEP_SUS_LINE3_COMPARISON_OSC_%sGAIN'%(g)] = (value) Will load at our earliest convenience.
