When I CTRL-C'ed out of the ESD charge measurement scripts earlier today I reset all of the ESD settings back by hand.  I didn't reset the L3 BIO STATE though because I was unfamiliar with these specific settings in the charge scripts (I focused on fixing the L3 BIO screen ESD switches, etc).  SO, when the IFO rapidly achieved NOM LOW NOISE after the TUES Maint period, these switches were in the wrong state.  Doh!!  Shiela tried her magic at transferring the ESD control back to ETMX in order to switch the incorrect ETMY settings, but it broke lock anyways.  Praxair is still on site, so we're trying to get back up and into Observe as soon as he's off site.  Sorry, that LL was on me!
