I recorded time series data of the L3 Dummy Mass using a QPD. Attempted to retrieve seismometer data (LHO H0 PEM LVEA), but found that a channel was saturating. After having it looked at (another cable not connected to the correct port), I confirmed we were recording data. Took another set of time series data with the QPD at the ITMY L3. After a cursory inspection of the results it appears that L3 Yaw and L3 Pitch are scaled versions of each other. Further inspections to be conducted to diagnose for possible electrical/electronic issues.
