The attached plots show:

1. The IPC errors from the corner to end stationfor the past year: ETM control signal
2. The IPC error from the end to the corner for the past year: Red transmitted light power
   The errors got really high after we added WFS and auto-centering.
3. The same as above but for the past 8 days. No IPC errors were detected, since the model was split 3 days ago.
