Niko, Darkhan,

We checked the alignment of the Pcal beams at EY by looking at the beam positions at the RxPD integrating sphere input port (in the Pcal receiver module). As was expected, the beams are well centered on the port.

Note: To do this check we needed to temporary turn on the Pcal laser (for which we removed the lock from the module with Bubba's permission). After the work was completed we switched off the laser and put Bubba's lock back on the Pcal AOM and laser power supply module.
