See attached screenshot.  Things I noted were:

• There is a glitch in both the EX and EY pump pressure on August 22 which likely corresponds to a HEPI trip described in alog 38313. 
• There is a large spike starting around August 12 that trends back to ~nominal which is likely due to HEPI being locked (aLog 38618).  The signal flatlines thereafter. Was the CS pump station turned off after all HEPIs were locked??  I failed to locate an aLog if this is the case.
• There is another glitch in both the EX and EY pump pressures Sept. 17, which is likely due to Hugh restarting the HEPI pump (?, no aLog yet although it was discussed in the morning meeting) after the Sept. 16 power outage (aLog 38675).
