The interferometer is locked in Nominal low noise and the PCAL X 1500 kHz line is off as of 22:55 UTC.  I hope that the BS ISI will not trip during the injections.  (alog 38382)

The interferometer unlocked just before 1187825964, so I think that 4 or 5 of these injections would have completed before it unlocked.  I don't know why it unlocked.

According to the guardian log (see attached), the first 5 of these injections made it in. The fifth one ended at 1187825913 (about 50secs before the lockloss). This should be enough injections for now. Thank you Sheila for coming in on a Saturday afternoon and locking the IFO for us!

Short version: I made omega scans for the 5 sets of injections that were done above andyou can find them here: https://ldas-jobs.ligo-wa.caltech.edu/~jrsmith/omegaScans/O2_detchar_injections/ (note that after the first set the rest of sub-directories of the start time for each set). 

Long version: The Injection files are here: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/detchar/. These are timeseries sampled at 16384 Hz and they start at the injection times listed in the original entry above. Times of the injections start 0.5s after times given in alog, and are separated by 3s each. Some simple Matlab to plot (attached) the injection file and print a list of times is: 

% Plot hardware injections
fnm = 'detchar_27July2017_PCAL_H1.txt';
data = load(fnm);
t = 0:1/16384:(length(data)-1)*1/16384;

figure;
plot(t,data)
xlabel('time [s]')
ylabel('amplitude [h]')
title(strrep(fnm,'_','\_'))
orient landscape
saveas(gcf,'injections.pdf')

% Print times of injections
t_start = 1187824000+0.5;
times = t_start:3.0:t_start+106;
fprintf('%.2f
',times)

To submit the omega scans I used wdq-batch like so: (gwpysoft-2.7) [jrsmith@ldas-pcdev1 O2_detchar_injections]$ wdq-batch -i H1 times-1.txt, then submitted the resulting dag to Condor. 

OmegaScan results are here: https://ldas-jobs.ligo-wa.caltech.edu/~jrsmith/omegaScans/O2_detchar_injections/

These will take some hours to run and we will then look at the results to see if there are any obvious unsafe channels. In addition we'll look statistically using hveto. 

This is the equivalent comment to the comment for L1's detchar injections hveto safety analysis on page 35675

I ran hveto_safety on the injections mentioned above, looking for coincidences within 0.1sec time window. 

The results of the analysis using >6 SNR omicron triggers can be found here: https://ldas-jobs.ligo-wa.caltech.edu/~tabbott/HvetoSafety/H1/O2/safetyinjections/D20170826/results/H1-HVETO_omicron_omicron-1187823990-125/safety_6.html

The configuration for the analysis can be found here: https://ldas-jobs.ligo-wa.caltech.edu/~tabbott/HvetoSafety/H1/O2/safetyinjections/D20170826/results/H1-HVETO_omicron_omicron-1187823990-125/H1-HVETO_CONF-1187823990-125.txt

I missed that there we 4 extra sets of injections, so I've redone the hveto safety analysis on the complete set of 180 injections.
