On Tuesday this week, X-End calibration of the PCal system was performed. The procedure is attached, as well as a photograph of the spot position on the RX PD integrating sphere aperture. The spot position looks similar to the previous measurement (alog 50215) with maybe some slight drift to the left. This will be monitored through the RX PD channel and checked again during the next measurement at EX.  

Analysis of the EX calibration confirms that the measurement is consistent with the general trend of the calibration parameters at this endstation.
