Set up the choppers as well as I could. We need more time to check steering and dechopping. However, we should be good for the program at hand which is beam to A, B and D. If RF group changes the chopper 1Y system (amplifier change or something else) tomorrow, then we need to check things again. Therefore I see no point in spending too much time now.

Figures 1,2,3 are A beam zero posed
Figure 4,5 are B beam
Figure 6,7 are D beam

A save with orbit lock and energy locks on for A Beam is done. 25767

started troubleshooting the chopper 1Y chassis after the system couldn't regulate the phase and amplitude earlier today
we removed 1 dB pad to have some headroom in the drive signal. This didn't last long as we had to come back after couple of hours with the same issue
