We spent this evening trying to get UIM to test mass length to length measurements.  We do this with no slow feedback to the top mass.  With optical lever damping on, we saturate the PUM at high frequencies, so it has been easier to make the measurements with OpLev damping off.  We have reasonable coherence from 5Hz down, saved as 2014-04-29_H1SUSETMX_L1_L2LPY_SwpetSine_OLDamp_Off_5Hz_to600mHz.xml

We are leaveing one measuremetn running on opsws6 with an envelope that we have tuned to get the low frequency part, saved as 2014-04-29_H1SUSETMX_L1_L2LPY_SwpetSine_OLDamp_Off_1Hz_down.xml.

We briefly tried using the UIM for feedback, with a theoretical plant inversion filter, with no obvious sucess. 

Kiwamu fixed the calibration of REFL_Y_CTRL, makiing it identical to REFL_X_CTRL.
