Main task at LHO is Robert's PEM test to distinguish between the Swiss cheese and the eye baffle as a source of 100 Hz noise in DARM from the HVAC, trucks, and other 8-18 Hz vibration as well as the transient 12 Hz combs.

   A2L Pitch above 0.4 and Yaw is around 0.8. Ran the A2L repair script while in the commissioning window.

16:00-16:05 UTC

Entered LVEA to de-energize turbo station connected to OMC, which drops the levitated turbo bearing.

This morning we rotated the beam splitter mount and aligned the green beam to the newly installed GigE camera. In theory the path of the green and the returned sled beam should overlap, but the camera didn't see the SLED even with the green well aligned. Given that the SLED shouldn't be too far off we tried installing a 800nm bandpass filter in front of the camera and randomly pitched and yawed the BS hoping something would show up, that didn't work. Many hours were spent trying to directly align the return sled light to the camera, but seeing the beam in the first place was a challenge. Since the pickoff BS is a 90:10, with 10% being the light reflected to the GigE camera. We tried swapping out the old sled for a new spare. Still, we didn't get anything. We also tried to point the camera in front of the steering mirror (before sled hits the pickoff BS), we couldn't get anything either. The next step to take here is probably go through some document to make sure that the camera can actually see 790nm. We left the green beam aligned to the camera, removed the bandpass filter (which was temporary borrowed), and closed out around noon.

The old 790nm sled S/N 07.14.256 was replaced with a spare S/N 07.14.254. Since the old one wasn't totally dead, we kept it in the spared box. So currently there's only one 790nm (new) spare sled left.

No issues relocking.  Had to accept ECATPLC2 SDF diff (H1:LSC-REFL_SERVO_IN1GAIN).  Screenshot attached.

Nothing obvious on FOMs.

OUTGOING OPERATOR: Jeff
CURRENT ENVIRONMENT:
    Wind: 8mph Gusts, 6mph 5min avg
    Primary useism: 0.05 μm/s
    Secondary useism: 0.18 μm/s
QUICK SUMMARY:  Jeff handed me a freshly relocked, observing IFO.  No unusual issues handed off. 

Scroll pumps #3, #4 and #5 were greased today.

A new relief valve was installed on unit #5.

Unit #2 still needs a check valve replaced.

Work done under WP 6541.

With J. Kissel, A. Viets, D. Barker; Re: WP 6567 and 6572.

The work listed on the above work permits is now done.

i. DMT yum updates and reboots are done. DMT is now running ROOT6 and gstlal-calibration-1.1.5.

ii. Channels were added to the framebroadcaster:

H1:CAL-CS_TDEP_ESD_LINE1_REF_A_TST_NOLOCK_REAL
H1:CAL-CS_TDEP_ESD_LINE1_REF_A_TST_NOLOCK_IMAG
H1:CAL-CS_TDEP_PCALY_LINE4_REF_C_NOCAVPOLE_REAL
H1:CAL-CS_TDEP_PCALY_LINE4_REF_C_NOCAVPOLE_IMAG
H1:CAL-CS_TDEP_PCALY_LINE4_REF_D_REAL
H1:CAL-CS_TDEP_PCALY_LINE4_REF_D_IMAG
H1:CAL-CS_TDEP_PCALY_LINE4_REF_A_TST_REAL
H1:CAL-CS_TDEP_PCALY_LINE4_REF_A_TST_IMAG
H1:CAL-CS_TDEP_PCALY_LINE4_REF_A_USUM_REAL
H1:CAL-CS_TDEP_PCALY_LINE4_REF_A_USUM_IMAG

iii. DMT calibration hoft and DCS aggregated hoft updated to now output these new channels:

H1:GDS-CALIB_F_S
H1:GDS-CALIB_F_S_NOGATE
H1:GDS-CALIB_SRC_Q_INVERSE
H1:GDS-CALIB_SRC_Q_INVERSE_NOGATE

starting from 1175978240 (Apr 11 2017 20:37:04 UTC).

That completes DMT/calibration updates and SRC detuning time dependent tracking in work permits 6567 and 6572 respectively.

On the LHO CDS web home page, I've added a SPI link to the GDS/DMT monitor status web page.

TJ restarted the DIAG_MAIN node. The available memory on h1guardian0 increased from 35GB to 43GB.

Because I'm not sure how long it'll take to make the MED screens and fully commission the new parts' settings until we have results, I just want to get an aLOG in there that confirms we've installed the front-end infrastructure changes to begin tracking the SRC detuning as a function of time.

This required modifying 
/opt/rtcds/userapps/release/cal/common/models/CAL_CS_MASTER.mdl
to include many new EPICs records that store various DARM loop model component values at the already-existing PCAL line frequency (7.93 Hz), and as a bonus, I also installed all of the infrastructure to compute the SRC detuning frequency in the front-end as well -- it was an easy extension of the existing software to calculate the optical gain and cavity pole frequency, following the math in T1700106 and LHO aLOG 35105.

I've installed values for these new EPICs records using svn up'd versions of
/ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Scripts/CAL_EPICS/writeH1_CAL_EPICS.m
/ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/Common/Scripts/CAL_EPICS/writeO2_TDEP_EPICS.m
/ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/DARMmodel/Scripts/computeEPICS.m

To do/aLOG:
 - Take screen shots of the new model infrstructure to show the implementation
 - Update TDEP MEDM overview screen to include the new math
 - Install demodulation parameters and lowpass filters for new 7.93 Hz demod
 - Install low-passes on F_S and Q_S output banks
 - Compare against GDS pipeline output

There were number of high frequency calibration lines injected using the automated Guardian scripts. These lines are injected using the Pcal at ENDX (ENDY is used for calibration purpose). The GPS time at which these lines were running are listed below:
