Supplementary notes for VIS folks:

• > Stepper motors of IP H1, H2, H3, and F0 yaw: calibrated
  • The details of the calibration curves are posted soon.
  • The results are stored here.
• > IP and BF LVDT polarities: confirmed
  • All of them were consistent with the design. No mistakes were found in the sensor polarities.
• > Cable tensions below the BF: slightly relaxed
  • We wanted to relax it since we were doubting this is the one of the reason of the issue in klog#9172. This is t be checked with transfer function measurement.
• > BF yaw picomotor: quickly inspected but still not working
  • We sent steps to the pico-driver and saw if the motor works with a fiber-scope. Then it seemed that the motor did not work, even though the sound was there.
• > ITMY tower current status: IP and BF are mechanically fixed
  • After the payload was released, the tower-part releasing buisiness is to be started.

• The photos are stored here.
• For a TEMPORARY use, I have prepared a dir for the health check measurement files (only for IP-L/T/Y, BF-L/T/Y):
  • /users/VISsvn/TypeAtower/ITMY/Measurements/TF/template/
  • /users/VISsvn/TypeAtower/ITMY/Measurements/TF/reference/
  • Please start from them and PLEASE DO NOT SET LARGE AMPLITUDE. The default amplitude are roughly tuned but it is roughly.
