Busy morning with:

• Sensor Calibration measurements (~33min), but took some extra time to bring back PCaly Cal Lines
• Transitioned SEI_DIFF back "ON" (to CORNER_DIFF_CPS state)
• Holiday Site Walk-through:  Total of 90min out of the Control Room (and about ~45min out of Observing to inspect the LVEA & end station VEAs).
• Time for lunch!
