| * IOO: === Discussion === * * What is the configuration for FPMI? * Locked Fabry-Perot? * Engineering run should not fix the configuration to FPMI. Configuration should be flexible. We assume June run as proposed. |
* Matrix diagonalization for ETMY seems to be much smoother than ITMY. Not sure the reason but ITMY seems to have more coupling. |
