Ops Day Shift Summary

TITLE: 09/27 [DAY Shift]: 15:00-23:00 UTC (08:00-16:00 PDT), all times posted in UTC

STATE Of H1: Observing at ~73 Mpc. The ifo has been locked 42 hours now.

SUPPORT: Mike

QUICK SUMMARY: The RF45 hasn't been acting up much (Laura suggested it probably was acting up between ~20:00-21:00 UTC, but the glitches was probably settle since it didn't set off the Verbal alarm) . Hardly any ETMY glitches alarm today. Wind speed ~10 mph. Seismic activity in 0.03-0.1 Hz band coming back to nominal.

INCOMING OPERATOR: Patrick

ACTIVITY LOG:

NO ACIVITY. It's been a boring shift (good for science!).

Even if less obvious than yesterday, it looks like there have been several periods in the last 24h with the 45 MHz EOM driver acting up again.

Ops Day Shift Transition

TITLE: 09/27 [DAY Shift]: 15:00-23:00 UTC (08:00-16:00 PDT), all times posted in UTC

STATE Of H1: Observing at ~70Mpc. The ifo has been locked for 36 HOURS!

OUTGOING OPERATOR: Ed M.

QUICK SUMMARY: 45 MHz EOM driver hasn't been glitching since shift started. Mike called to give advice on how to fix GraceDB query issue. I'm reading 0 mph wind speed everywhere on the PEM weather medm screen. A little bit of seismic activity in 3-10 Hz band which seems to correspond to the slight drop in BNS range but otherwise everything else looks quiet. The ifo is locking and going strong.

I have patched the ext_alert.py script to catch SSLError exceptions and retry the query [r11793]. The script will retry up to 5 times before crashing completely, which is something we may want to rethink if we have to.

I have request both sites to svn up and restart the ext_alert.py process at the next convenient opportunity (the next time it crashes).

Narrow lines in H1 DARM in O1 week 1
Executive summary: 
  • In regard to narrow lines, early O1 data resembles early ER8 data: a pervasive 16-Hz comb persists throughout the CW search band (below 2000 Hz); there is a notable 1-Hz comb below 100 Hz (0.5-Hz offset); and other sporadic combs persist.
  • On the other hand, there are distinct improvements: noise floor is cleaner nearly everywhere and substantially lower in the 10-70 Hz band; non-linear upconversion around quad violin modes and harmonics is much reduced; some combs and isolated lines have disappeared; and the OMC alignment dither frequencies have moved out of the CW search band (hurray!).
  • Oh the third hand, new artifacts have appeared or strengthened: a sporadic 8-Hz comb suspected before is confirmed; a 1-Hz comb (no offset) has emerged below 70 Hz; a broad bulge appears in the 1240-1270 Hz band.
Details: Using 104.5 hours of FScan-generated, Hann-windowed, 30-minute SFTs, I have gone through the first 2000 Hz of the DARM displacement spectrum (CW search band) to identify lines that could contaminate CW searches. This study is very similar to prior studies of ER7 data and ER8 data, but since this is my first O1 report, I will repeat below some earlier findings. Some sample displacement amplitude spectra are attached directly below, but more extensive sets of spectra are attached in zipped files. One set is for O1 sub-band spectra with labels (see code below), and one set is an overlay of early ER8 spectra (50 hours) and the early O1 spectra. As usual, the spectra look worse than they really are because single-bin lines (0.5 mHz wide) appear disproportionately wide in the graphics A flat-file line list is attached with the same alphabetic coding as in the figures. Findings:
  • A 16-Hz comb pervades the entire 0-2000 Hz band (and well beyond, based on daily FScans)
  • A typically much weaker and sporadic 8-Hz comb (odd harmonics) is also pervasive - previously suspected, now confirmed (all harmonics are labeled in figures, even when not visible)
  • A 1-Hz comb with a 0.5-Hz offset is visible from 15.5 Hz to 78.5 Hz (slightly wider span than before)
  • A new 1-Hz with zero offset is visible from 20.0 Hz to 68.0 Hz
  • A 99.9989-Hz comb is visible to its 8th harmonic (was previously visible to its 13th harmonic)
  • The 60-Hz power mains comb is visible to its 5th harmonic (was previously visible to its 9th harmonic)
  • There is a sporadic comb-on-comb with 0.088425-Hz fine spacing that appears with limited spans in three places near harmonics of 77, 154 and 231 Hz (ambiguity in precise fundamental frequency)
  • There is a 31.4149-Hz comb visible to its 2nd harmonic
  • The OMC alignment dithers have been moved to above 2000 Hz (thanks!)
  • Upconversion around the quad violin modes and their harmonics is much reduced, although the strengths of the higher harmonics themselves remain high. To be more specific, the fundamental and higher harmonics of the upconversion itself (integer harmonics) due to the fundamental violin harmonics are highly suppressed, while the higher harmonics of the violin modes themselves (not integer harmonics) remain high.
  • A number of previously seen combs are no longer apparent: 59.3155 Hz, 59.9392 Hz, 59.9954 Hz and 75.3 Hz
  • A variety of single lines have disappeared, and new ones have appeared (see attached line list)
  • Compared to early ER8 data, the noise floor is slightly lower in most of the band and significantly lower in the 10-70 Hz band, but there is a significant new bulge in the 1240-1270 Hz band

Keith has found:
"There is a sporadic comb-on-comb with 0.088425-Hz fine spacing that appears with limited spans in three places near harmonics of 77, 154 and 231 Hz (ambiguity in precise fundamental frequency)"

Using the coherence tool, we have seen coherence between h(t) and a number of auxiliary channels that shows this comb around 77 Hz. Seems to be around the input optics, in channels:

The structure at 76.4Hz Nelson listed some channels for above shows up in at least 50 other channels. 

Greatest coherence is consistently at 76.766 Hz, second greatest is (mostly) consistently at 76.854Hz. 

Spacing between the two combs is about 0.0013Hz.

The epicenter seems to be the INPUTOPTICS/the SUS-BS and SUS-ITM* channels, like Nelson said (see below for fuller list).

The plots above are pretty typical, but I have plots for all channels listed and can post any more that are useful. Most or all channels showing the comb with max coherence greater than 0.1 are listed below. Max coherences over 0.2 are marked below as strong, and max coherences under 0.15 as weak. Those marked strongest are around 0.22. I haven't included anything of max coherence <0.1 but I'm sure there are many.

The 99.9989Hz comb Keith found (designated H) appears in 109 channels (list is attached). Coherence is uniformly greatest at the ~500Hz harmonic, with many channels approaching .7 and greater, drops off sharply at the ~600Hz and ~700Hz, and is invisible after 700. (See spreadsheet titled "comb_H_sigcohs_wk1.xslx" for a list of cohering channels by line, with coherence value.) 

At all harmonics except the ~300Hz, the structure manifests in the signal and the coherences as two lines .001Hz apart, but if I recall correctly .001Hz is the resolution of the frequency series, so it's safer to say that this is a bulge with .001Hz < width < .002Hz. At ~300Hz, almost all the cohering channels with data in that range show a bulge of width about 0.5Hz (see attached "disjoint_plots" for a comparison of typical channels by harmonic). This bulge, and the fact that it appears in all the same channels associated with the rest of the comb, makes me think that the fundamental may be the bulge at ~300Hz and not the line at 99.9989Hz. An interesting feature of the bulge is that in many cases, it has a prominent upward or downward spike at 299.96Hz, which is just the place the line would be if it were there (see "bulge_w_spike.jpg").

More to come re: changes in week 4 data, patterns in cohering channels, and the spike.

Day Shift Summary

TITLE: 09/26 [DAY Shift]: 15:00-23:00 UTC (08:00-16:00 PDT), all times posted in UTC

STATE Of H1: Observing at ~75 Mpc

SUPPORT: Mike

QUICK SUMMARY: Less 45MHz glitches during my shift. DHARD Y boost turned off (as MIke requested). Wind speed coming below 20 mph. Several small earthquakes throughout the shift.

INCOMING OPERATOR: Patrick

ACTIVITY LOG:

18:07 Jodi to high bay area looking for contamination control stuff. Still observing.

18:14 Jodi out

19:08 Switched the ifo to Commissioning to turn off the DHARD Y boost filter. 

19:09 Back to Observing

22:33 A big tour group starting to march in the control room. ~20 adults. There was also a 5.1M earthquake at Pacific-Antarctic Ridge arrving at about the same time so there were glitches in DARM during the time. Just in case anyone wants to look into outreach noise. 

22:46 Group leaving.

23:00 Handing off to Patrick.

Ops Eve Beginning Shift Summary
TITLE: 09/26 [EVE Shift]: 23:00-07:00 UTC (16:00-00:00 PDT), all times posted in UTC
STATE Of H1: Observing at ~71 MPc
OUTGOING OPERATOR: Nutsinee
QUICK SUMMARY: Lights appear off in the LVEA, PSL enclosure, end X, end Y and mid X. I can not tell from the camera if they are off at mid Y. Seismic in 0.03 - 0.1 Hz band is coming down from a small peak to ~.7 um/s. Seismic in 0.1 - 0.3 Hz band is around .09 um/s. Wind speeds are less than 20mph, may be coming down.

GWIstat has a new web location
The LIGO-Caltech systems folks have set up a dedicated account for GWIstat and the associated processes that Chad set up to feed it information about the LIGO detectors, running on the ldas-grid machine at Caltech.  The new URL for the GWIstat display is https://ldas-jobs.ligo.caltech.edu/~gwistat/, and it does not require ligo.org authentication any more.  The old URL now redirects to the new URL.  (At least I think so -- let me know if you run into any problems.)

Due to moving GWIstat to its new location, the durations of the current observing segments are not reported correctly.

HWInjReport daily run 1127247535 - 1127333935

Parameters:

GPS Start Time = 1127247535 # Beginning of time span, in GPS seconds, to search for injections
GPS End Time = 1127333935 # Ending of time span, in GPS seconds, to search for injections
Check Hanford IFO = True # Check for injections in the Hanford IFO frame files.
Check Livingston IFO = True # Check for injections in the Livingston IFO frame files.
IFO Coinc Time = 0.01 # Time window, in seconds, for coincidence between IFO injection events.
Check ODC_HOFT = True # Check ODC-MASTER_CHANNEL_OUT_DQ channel in HOFT frames.
Check ODC_RAW = True # Check ODC-MASTER_CHANNEL_OUT_DQ channel in RAW frames.
Check ODC_RDS = True # Check ODC-MASTER_CHANNEL_OUT_DQ channel in RDS frames.
Check GDS_HOFT = True # Check GDS-CALIB_STATE_VECTOR channel in HOFT frames.
Report Normal = True # Include normal (IFO-coincident, consistent, and scheduled for network injections and consistent and scheduled for IFO injections) injections in report
Report Anomalous = True # Include anomalous (non-IFO-coincident, inconsistent, or unscheduled) injections in report

All injections found were UNSCHEDULED CBC injections in H1. There were no injections found in L1. All injections were consistent.
