13:50UTC addressing RF45 AM issue that has been ongoing for about 4.5 hours. Mike L and I decided to try a reduction in the LSC-MOD_RF_45_AM gain by 1dB to as per Stefan's aLog https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=21716
Mid-Shift Summary: IFO Locked @ 64Mpc (lower than normal due to funny business visible in DARM). No obtrusive Seismic or wind activity. 2 ETMY glitches. Some increasing activity in the lower DARM frequencies are causing drops in range. It just keeps bouncing up and down (see screenshots) Is this a combination of bounce and roll modes ringing up? This was the same activity that I noted in my transition summary. Is it from anthropogenic noise?
So this was due to the 45Mhz RFAM issue that H1 has been experiencing. With Mike L's help, I got an education on what it is and how to try and tame it in the days prior to it being rectified once and for all.

STATE Of H1: Observing
OUTGOING OPERATOR: Patrick
QUICK SUMMARY:. IFO Locked at 68Mpc/22.9W. No injections are running. All lights are off in LVEA, MID, END and PSL. Wind is <10mph. Microseism seems to be riding steady at ~.1um/s for the last few hours following an earthquake. EQ seismic took a little hop from ~ .2 um/s to .1um/s due to a small earthquake in the Portugal area. It appears that at 07:09UTC there was some raised level of noise activity in DARM from 25Hz and below. This only lasted about 1 minute.
TITLE: 09/25 [EVE Shift]: 23:00-07:00 UTC (16:00-00:00 PDT), all times posted in UTC STATE Of H1: Observing, ~67 MPc SHIFT SUMMARY: Recovered from two lock losses. The cause of the first is unclear. The second was likely from a 6.2 magnitude earthquake in Chile. After recovering from the earthquake I put it into commissioning mode to allow Chris to do hardware injections while LLO was down. He is done and we are back to observing. INCOMING OPERATOR: Ed
Terramon and GW Stat on nuc1 are down due to some kind of authentication issue.
We tested a set of waveforms to see if they would saturation the ETMY ESD. Test the 15Hz waveform Previously we have tested a waveform that began at 30Hz, see aLog 21838. It was requested we try it from 15Hz instead of 30Hz.

The ETMY alert happened a bit after the injection happened. SO I waited, I repeated the same injection, and there was no alert. I did one of these injections with a padding of 10 minutes so if the search groups are going to followup one of these injections in more detail this would be a good choice: awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior0_1126259455.out 1.0 -d -d >> log3.txt # gave this guy a bit of time The start time of this injection is: SIStrOpen: Waveform starts at GPS=1127281956, epoch=0, sample=0 Testing the other nine waveforms Then I tested the remaining 9 waveforms by beginning with a scale factor of 0.3333 and incrementing to 1.0. I did these with little spacing between the injections so I do not think this set is worth the analysis groups following up. However, I think the injections with scale factor 1.0 should be looked at for ESD saturation (I believe Andy has a script for that): awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior1_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior1_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior1_1126259455.out 1.0 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior2_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior2_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior2_1126259455.out 1.0 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior3_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior3_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior3_1126259455.out 1.0 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior4_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior4_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior4_1126259455.out 1.0 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior5_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior5_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior5_1126259455.out 1.0 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior6_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior6_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior6_1126259455.out 1.0 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior7_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior7_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior7_1126259455.out 1.0 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior8_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior8_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior8_1126259455.out 1.0 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior9_1126259455.out 0.3333 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior9_1126259455.out 0.6666 -d -d >> log3.txt awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior9_1126259455.out 1.0 -d -d >> log3.txt The start times of these injections: SIStrOpen: Waveform starts at GPS=1127282013, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282066, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282120, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282173, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282226, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282278, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282326, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282377, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282422, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282476, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282517, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282577, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282631, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282681, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282727, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282770, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282819, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127282964, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283007, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283048, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283089, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283160, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283204, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283245, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283292, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283338, epoch=0, sample=0 SIStrOpen: Waveform starts at GPS=1127283440, epoch=0, sample=0 As I did these injections I had the SUS-ETMY_L3_ESDOUTF_LL_OUT channel open in dataviewer. I did not see any injection go above the 90000 counts. The highest was posterior0*.out which was near 80000 counts.
I am going to follow up the injections I passed to Chris. Assuming the "start time" is the time at the 1st sample of the injection file (and not the 1st non-zero sample) the end times of the increasing amplitude posterior0 injections should be around
The only ETMY overflows during the injection periods were: 1127278436.8 1127280154.9 (also overflowed ETMY L2 and OMC DCPD) 1127282847.5 None were related to the injections.
John V. has also provided 10 waveforms that I used for testing. The waveform single-column ASCII files that contain the h(t) time series can be found in the hardware injection SVN here: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/Inspiral/${IFO}/posterior*.out
And the corresponding XML parameter files can be found here: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/Inspiral/posterior*.xml
I will post time series plots of the waveforms as a comment later.
06:20 UTC Chris is done with hardware injections, back to observing mode
I'm done with the hardware injection tests. More details in upcoming aLog entry.
04:20 UTC Taking out of observing to allow Chris to test hardware injections
L1 is down at the moment. I am beginning some single-IFO hardware injection tests at H1 now.
03:28 UTC locked on DRMI briefly, loss lock, tripped BS ISI stage 2 GS13 04:09 UTC Back to low noise 04:16 UTC Back to observing mode

23:48 UTC tour in control room 23:58 UTC video3 frozen, rebooted 00:26 UTC last of tour left control room 01:10 UTC problems with operator0 workstation, rebooted twice 02:06 - 02:11 UTC stepped out of control room Still in observing mode at ~ 70 MPc.
A tour group was on site this afternoon. Arrival time at LSB = ~3:00 PM. Departure time = ~5:15 PM. Group size = ~26 adults. Vehicles at the LSB = ~12 passenger cars. The group walked to the overpass near 4:15 PM and visited the control room near 4:45 PM.
23:23 UTC Back to observing. Only intervention required was moving the BS in pitch at LOCK_DRMI_1F. Cheryl states that it is acceptable that the 'Continuous Wave Inj Signal' on the Ops Overview is red and stating 'No Injection'.
