On Tuesday we performed an EY end station calibration. The measurement procedure/log and a picture of the beam alignment on the RX integrating sphere aperture are attached. The spot positions seemed slightly high compared to the last measurement on 06/04 (49868) but the phone used picks up a bit of IR light, which has fooled us before on where the spot positions actually are. I will keep an eye out for clipping on the RX aperture until the next end station calibration.

Analysis of the calibration data seems in line with the last few calibration measurements we've performed.
