Yesterday I aligned the IR transmission to the TMSY ISC table QPDs.
It was easy to bring the beam on both of the QPDs using M14 (downstream pico mirror). I made a very small PIT adjustment using M4 (upstream) before the IFO decided to not to cooperate.
Today I was just fishing for a good flash and found one (attached). Seems like both of the QPDs are reasonably centered: [P, Y]=[0.05, 0.18] for QPDA, [-0.1, -0.1] for QPDB.
And apparently we're still receiving IR light on ISCTEY, even though I didn't touch periscope. This is good enough.
