Today we took calibration measurements of both end station PCals.  See full reports attached if interested.  In summary, the newest calibration for EX looks good with the new RX/WS and TX/WS ratios being less than a tenth of a percent from the old values.  For EY, the ratios are ~0.5% from the old values.  Looking at the raw plots, there is some biased noise showing up from the WS and a very suspect shelf that comes and goes during separate measurements.  We would like to retake the EY measurements at the next availability since Darkhan and I believe that it is possibly due to a funky power source we have been using with the WS current amplifier (a 3-way extension cord with a power strip plugged in).
