Below I summarize the main highlights of this shift:
- The duty cycle factor during this week was 73.6%.
- The wandering lines showed up due to SQZ, which were also seen in H1:PEM-CS_MAG_LVEA_OUTPUTOPTICS_X_DQ.
- The variance of ASC DHARD yaw control seems to be correlated with that of the VCO frequency.
- The line of Pcal X TX did not sit on the top of the line of RX at 500 Hz on May 2, 3, and 4th although the line sat on April 29th and May 5th. The Pcal plots are not generated on April 30th and May 1st.
