Now that we've got some updated alignment and other configuration changes to the IFO this week, I wanted to check in on the jitter cleaning.  It looks like it's still working fine. 

So, the fact that our GDS-CALIB_STRAIN_CLEAN range is about the same as our CAL-DELTAL_EXT range (instead of the CLEAN looking higher than CAL-DELTAL range) is likely more due to the time dependent calibration factors, and not due to problems with cleaning.  Tuesday night, the jitter 'cleaning' was adding noise, when we were clipping a beam somewhere.  However now that we're no longer clipping, the input jitter coupling is back to about how it was.

The first attachment shows the working cleaning in spectral form, and the second attachment shows it in the range channel time series with colors roughly matching.
