Attached are plots of dust counts requested from 5 PM May 30 to 5 PM May 31.

The dust monitor at location 14 in the LVEA (H2 PSL enclosure) is indicating a calibration failure.

After 45 minutes or so, GV5 "cammed" closed -> As such, I went ahead and valved-in the YBM MTP for the weekend.  

For future reference;  use 5-10 psi for GV5 soft close instead of 10-15 psi (each pneumatic valve is unique, observed range varies between 15-25 psi to cam close)

We have initial alingments for TMS-Y, ITM-Y, and ETM-Y. The green light from the TMS was observed at ITMY, the reflected light from ITMY was observed at ETMY, and light was returned from ETMY to ITMY.

The initial pointings in (P,Y) convention:

TMSY - (-14400, 9170)

ITMY - (246.0, -275.0)

ETMY - (-140.0, 198.0)

For the 200W laser

There is a broad peak at 4kHz in the ISS rpn plot which appears in the 200W laser's rpn plot as well. For comparison, the last time I took these plots for the 200W laser as 10/30/2012.

I set the damped TFs running last night to check effectiveness of new damping settings. Measurements done when checked at 7:45 am. Plots pending.

This is a late alog from yesterday morning. Before the gate valve was open I went out to end y to adjust the transmontane position to see if the 10 uW beam on the refl pd was a gobst beam.  With a better alignment of the Trans mon there were:

8.87 mW green power before the EOM, 1.35mW onto the refl PD and -0.220 volts on the dc output.

We are ready for closing the WFS loops.

We excited MC3_M1_P at around 3 Hz with an amplitude of 10 counts by AWG. Monitoring the peak in DTT we minimized a signal leaked in the Q-phase. The WFS-A looked perfect and we didn't re-adjust it at all. As for WFS-B we adjusted segment 2 (whose cable was replaced) and segment 3. Plus, later on we flipped the sign of all the segments by further rotating the demod phases by 180 degs in order to have the same signal sign as that of WFS-A.

Modified detailed CDS overview screen to include h1asc model.  Added h1asc .par and .ini files to the data concentrator master file, restarted the data concentrator.  Restored the symbolic link of the SITEMAP.adl file to the proper place in userapps directory. 

MC1 MC2 and MC3 Phase 3b M1 to M1 transfer functions have been measured over the past weekend. They all show good agreement with model and previous measurements.

The attached files are showing comparison between model, phase 3a and 3b (except for MC2 3b vs 3b)

Summary of important events:

- Sheila found the Y-ITM cameras unplugged, she plug them and turn them on.
- LVEA crane maintenance. Talk to Ski or John for more details.
- Apollo working in X End, which (I guess) trigger the dust monitors several times over there.
- Y arm: GV 1,5,6,9,10,11,12,17,18 open
- The main gate seems broken, Ski said will take care of it - (Now, 16:00, is working well)
- PSL died ~2PM, not clear reason why. For more details talk to Michael R.
    NOTE: no alarm when this happen, I think we should have an alarm for events like this.
- PSL recovered ~3PM  ( Go hIFO! )

The green beam is officially on ITMY again! 

Unfortunately we no longer have the baffle photodiodes at our disposal, so we can't reproduce the OAT calibration. The rough alignment was achieved by viewing the beam on the pitch and yaw axes of the ITMY and averaging the counts on either side of the optic. 

measurements - (pitch, yaw) in counts:

The nominal TMS alignment is (-14400, 9170). 

Redoing the damped TFs on X1 with new damping filters and gains per LHO alog 6548.
