As per Gautam's request, I list the changes that were made since he left:
1. The AOM driver was connected to a signal generator.
2. The first order beam from the AOM was coupled into the PMC while the zero-order beam is blocked. We might want to keep this configuration if the pointing stability is adequate.
3. c1psl got Burt restored to Dec 1st.
4. Megatron got updated.
Currently, c1susaux seems unresponsive and needs to be rebooted.
