The X arm was misaligned and the Y arm was locked. ITMY/ETMY/BS were shook in pitch and yaw separetly, at 0.1Hz with and amplitude of 0.5 using the lock in oscillator. Initially the beam on QPD2 moved a lot and gave large and different values, but after implementing a centering lock that will be described in Chiaki's klog, the values settled. The number of counts/urad in the QPDs at TMSY are recorded below. The values with an asterisk have ambigous phase.

These results look like they can be diagonalised to be used in a feedback loop which is the next step.
