No issues coming back up.

PI mode 28 rang up and I couldn't find the right phase value fast enough.

Ran through a painless IA.  Adjusted ISS diffracted power as it was complaining that it was low.  Accepted SDF diffs in attached screenshots.  ISS refsignal was, of course, me. The other two I am not sure about.

Cause unknown.  Lock gave up at 71 hours and 10 minute old.

Wind has calmed down a bit and the range has come up some.  We just rolled over to 70 hours locked.

SHIFT SUMMARY: Abnormal noise in 3-10 and 10-30 Hz seismic BLRMS correlated with noise in range for a few hours before noon. Also heard an airplane at 20:08 UTC that may have correlated with noise in DARM.

16:45 UTC PI mode 23 came up coincident with large glitch in DARM. Spike in 3-10 and 10-30 Hz CS Z axis seismic BLRMS.

20:08 UTC Airplane heard in control room. Possible correlated noise in DARM.
20:41 UTC Gerardo to mid Y for scroll pump maintenance work. Nothing noisy.

Starting CP3 fill. LLCV enabled. LLCV set to manual control. LLCV set to 50% open. Fill completed in 1072 seconds. TC B did not register fill. LLCV set back to 19.0% open.
Starting CP4 fill. LLCV enabled. LLCV set to manual control. LLCV set to 70% open. Fill completed in 128 seconds. LLCV set back to 37.0% open.

The range has been degraded for the last few hours coincident with abnormal noise in the 3-10 and 10-30 Hz seismic BLRMS. The noise appears to have subsided for now and the range has recovered. PI mode 23 was ringing up coincident with glitches in DARM during this period.

The full suite of summary pages comparing C01 data against the online C00 frames are available here (requeres LIGO.ORG credentials). Note, these pages currently cover data between 30 November 2016 and 10 March 2017, inclusive.

Notes:

• The front page, linked to above, contains a number of goodies. Probably the most important is a full set of timeseries trends of PCAL/h(t), showing both magnitude and phase, at both interferometers. The blue trace shows C00 data, the red trace shows C01, and the green trace corrects C01 for the time-varying coupled cavity pole frequency, which is tracked online. The plots made for Hanford data are attached below. (As expected, tracking f_CC puts the magnitude of these line ratio trends to unity at 331.9 and 1083.7 Hz, although there is a phase offset above 1 kHz.)
• Also on the front page is a link to an overview of C01 analysis segments. I put this together based on email traffic in the CBC group, in which some PyCBC people were wondering how segments affect the searches.
• There are daily summaries between 30 November and 10 March at both instruments. These are organized into four tabs: a summary showing ASD ratios, BNS range, and segment information; a snapshot of kappa timeseries trends; a higher-level view of the BNS range (including its derivative with respect to frequency and the cumulative fraction of SNR over frequency); and a fourth tab showing zoomed-in plots at each PCAL line.
• At the request of several people, each page now also links back to the homepage.

The scripts I used to generate some of these plots live in the calibration SVN repo and use GWPy (which can be sourced on any of the LDAS clusters by sourcing the gwpy.env script in that repo). The rest of it was all done using the gwsumm, the same infrastructure used to make Duncan's DetChar summary pages. (To see how a specific page was made, you can always hit "How was this page generated?" at the bottom of the page.)

WP 6562; Nutsinee, Kiwamu,

As a follow up of Aidan's analysis (35336), we did a simple measurement in this morning for determining the HWS coordinate.

- Preliminary result (currently being double checked with Aidan):

• The vertical coordinate needs to be flipped. This is consistent with what Aidan reported (35043).
• The horizontal coordinate does not need to be flipped. This is opposite to what Aidan concluded based on a CO2 measurement (35336).

[Measurement]

• We tilted ITMX in yaw toward positive values by 15 urad. 
• We then observed the displacement in the Hartman spots in HWSX.
• The spots moved toward the right (i.e. all the vectors in the Hartman image pointed toward the right).
  • This indicates that there is no need to switch the left and right.

[Verification measurement]

• We tilted ITMX in pitch this time toward negative values by 15 urad.
• The spots moved upward (i.e. the vectors pointed upward).
  • This means that the y coordinate is up-side-down. The y-axis needs to be flipped.
