Thomas Vo, Sheila Dwyer

We started out pre vent/discharging measurements in tonight.  

• First we ran the automated version of the ESD actuation strength measurements described using the attached script, we got data for all 4 ESDs.  
• We made an attempt to transition DARM control to the ITMX ESD but noticed that we are missing IPCs that would allow us to send DARM to the ITMs. 
• We intentionally unlocked the IFO so Thomas could take some HWS measurements for the ETMs, but has difficulty getting a reference at DC readout. While we were moving the PZT misalingment biases the interferometer became misalinged and unlocked.  We will need to investigate this before continuteing the HWS measurements.
