ITM03 and ITM11 have both ears bonded on, and are back in their cake tins for curing.
ITM03 S1 also had its fc pulled, and coating inspected as seen in T1400043. A “ thick balanced layer” was re-applied to face, leaving a small part at 12 o’clock position off for welding alignment. 
Pulled PEN-ETM08 out and staged, will get at least one ear onto it tomorrow morning (friday). 
CP05: Fiducial measurement staged and completed (had to get granite table moved to bonding lab, and equipment set up etc.) Left CP05 in flipper under flow bench for getting its prisms on next week. Measurements are on the dcc under E1400054.  
LHO large optics inventory: Went through cabinets here, then updated nebula location and install vs spare status for CPs, ITMs, LHO PEN-ITMs, LHO PEN-ETMs, SRMs, SR2s, PRMs, and PR2s. 

Just for your information, from Jan 30th-Feb 6th the IMC has had a duty cycle of 81.5% (according to the ODC) and attached are the ASD of IMC-F and IMC-X for this period (i.e. all the good time in the past week). Plotted are the median ASD of this time period with the 5th and 95th percentile showing the shaded regions. As you can see the spectra look quite stable. 

I have changed the controls account desktop DTT icon to read DTT-debug, and have redirected it to start a test version of diaggui which should solve a critical bug that has generated complaints for the last few years.  The bug involves the inability for diaggui to properly restore Reference traces to the plot window when read from a .xml file.  This should show up on new logins of the control room computers running Ubuntu.

The command line invocation of diaggui still opens the non-test version.

Please use the desktop DTT-debug icon if you would like to test this.  Feedback is appreciated.  Once further testing is complete, a new version of the gds tools will be released.

Reloaded the Local to Cartesien Matrices to correct errors (per T1000388).

This changed the Location Monitor numbers mostly in sign but some minor magnitudes too. The X Y RX & RY values changed signs.  I reset the targets with the ISI off (and HEPI position loops on).  The Rz value changed by a couple urads.

I added back the Beckhoff channels minus a new list of ones that appeared to be changing too quickly. This time the update rate appears reasonable. Conlog is now monitoring 97,308 channels (target_grep_channel_list_minus_fast_beckhoff.txt). The list of fast channels I removed is also attached (beckhoff_ro.txt).

   We moved the HLTS suspension SR3 into position to have the metal Bottom Mass replaced with the Glass Optic. We took height and blade tip breakoff measurements as a pre-installation base line. All measurements are within tolerances. 

Measurement Point            Target/Tolerance  	                         Measurement 
Top Blade Wire Breakoff       806.12mm	                                 804.93mm, 805.89mm 
Bottom of T-Block                 552.23mm	                                 552.60mm
Top of Intermediate Mass     461.63mm	                                 461.63mm
Lower Blade Wire Breakoff   608.84mm tip coplanar <0.5mm  607.75mm, 608.11mm, Coplanar = 0.36mm
Top of Bottom Mass              291.0mm +-1mm	                         291.17mm

   The next step is to center and adjust the OSEMs, and then run Phase 2A Transfer Functions.  

Corrected daqdrc file, restarted daqd on h1nds1.

  In preparation for installing sensor correction I took a ground to platform transfer function to see what kind of coherence we have, short answer is lots from 0,1 to a few hertz

The aLOG will be down for maintenance tomorrow at noon (pacific time).

Please post or save your log entries before the maintenance.

I commented out the DC watchdog components in /opt/rtcds/userapps/release/cds/h1/alarmfiles/h1cds_iop_sus_watchdog_b123.alhConfig.

Getting alignment targets from end X and installing them on TMS at end Y.

Frame writer 1 daqd and nds1 daqd were restarted to read new daqdrc files to allow writing of raw minute files in the proper place, following moving of old files to a different file system.

A horizontal 4" witness plate (wafer) and horizontal 1" optic (S/N 1247) were placed near the center of the SEI table on Feb 5th. A vertical 1" optic (S/N 1245) was mounted on the HR side of SR2. A vertical wafer still needs to be set near SR2. 

Important notes: Witness samples were not placed immediately after the chamber was opened. Jeff did some cleaning before SR2 was installed and the wafers and optics were placed. Also, the 1" optics were removed from their PET G containers, put in PEEK holders, double bagged, and stuck in a bag with other tools before going in chamber. I didn't see obvious scratches in the First Contact, so hopefully the samples weren't damaged. 

Maybe Stefan turned these off, I didn't catch such in the alog.  I thought I left these in some Isolation state yesterday as Stefan wanted PRMI asap.

ITMY is damping with a Stage2 trip from GS13 limits.  The BS has no trip indicator but is damping only.

The HEPIs here are running normally.
