I increased the amplitude gain of the TST SUS LINE at 17.6 Hz line to 0.17 from 0.085 using the same line command from LHO:71947. The change took place at GPS 1383694441.

This change was in response to LHO:74113 and LHO:74136. It's meant to be a temporary measure until we can try the new MICH FF without the 17.7Hz zp pair (LHO:74139).

I've attached a scope of the ETMX L3 SUS line uncertainty to show that it's now down to about 0.5%, which is below the 1% threshold implemented by the GDS pipeline (LHO:72944).

Here is the command I used:
val=0.17 && caput H1:SUS-ETMX_L3_CAL_LINE_CLKGAIN $val && caput H1:SUS-ETMX_L3_CAL_LINE_SINGAIN $val && caput H1:SUS-ETMX_L3_CAL_LINE_COSGAIN $val && caput H1:CAL-CS_TDEP_SUS_LINE3_COMPARISON_OSC_CLKGAIN $val && caput H1:CAL-CS_TDEP_SUS_LINE3_COMPARISON_OSC_SINGAIN $val && caput H1:CAL-CS_TDEP_SUS_LINE3_COMPARISON_OSC_COSGAIN $val
