Tested PCALX with new inverse actuation filter
Summary:

We had single-IFO time so I tested the new inverse actuation filter for PCALX. WP5530

Sudarshan and I believe we tracked down the factor of 2 and sign error from the initial PCALX test, see aLog 22160. We wanted to do this test to confirm that.

CBC injections:

The waveform file is: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/Inspiral/H1/coherenttest1from15hz_1126257408.out

The XML parameter file is: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/Inspiral/h1l1coherenttest1from15hz_1126257408.xml.gz

I did three CBC injections. The start times of the injections were: 1128303091.000000000, 1128303224.000000000, and 1128303391.000000000.

The command line to do the injections is:
ezcawrite H1:CAL-INJ_TINJ_TYPE 1
awgstream H1:CAL-PCALX_SWEPT_SINE_EXC 16384 coherenttest1from15hz_1126257408.out 1.0 -d -d >> 20151006_log_pcal.out

I have attached the log. I had to change the file extension to be posted to the aLog.

DetChar injection:

I injected Jordan's waveform file: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/detchar/detchar_03Oct2015_PCAL.txt

The start time of the injection is: 1128303531.000000000

The command line to do the injections is:
awgstream H1:CAL-PCALX_SWEPT_SINE_EXC 16384 detchar_03Oct2015_PCAL.txt 1.0 -d -d >> 20151006_log_pcal_detchar.out

I have attached the log. I had to change the file extension to be posted to the aLog.

Chris Buchanan and Thomas Abbott,

Quick follow-up with omega scans. It looks like most of the power is seen in GDS-CALIB_STRAIN about eight seconds after each listed injection time, consistently for each of these three injections. Doesn't look like there are omicron triggers for these times yet, but omega scans for GDS-CALIB_STRAIN are attached.

Full omega scans generated here:

For complete documentation of the detchar safety injections:

The injections are 12 sine-gaussians, evenly spaced from 30hz to 430hz, 3 seconds apart with a Q of 6. There are three sets with increasing SNR of 25, 50, 100 (intended). However, the SNR is limited by the PCAL acuation range at higher frequencies.

To generate the waveforms I used the script written by Peter Shawhan / Andy located here: https://daqsvn.ligo-la.caltech.edu/websvn/filedetails.php?repname=injection&path=%2Fhwinj%2FDetails%2Fdetchar%2FGenerateSGSequencePCAL.m

I tuned the injections to stay within the PCAL actuation limits referenced in Peter Fritschel's document https://dcc.ligo.org/LIGO-T1500484.

The intended time (seconds from start time of injections), freqency, snr, and amplitude (in units of strain) for all injections are pasted below:

Here are the SNR of the CBC injections using the daily BBH matching filtering settings:

end time               SNR   chi-squared  newSNR
1128303098.986  20.35  32.86            19.86
1128303231.985  22.62  32.73            22.10
1128303398.985  23.25  21.05            23.25

Expected SNR is 18.4.

Though a recovered SNR of 20 (about 10% percent difference from 18.4) is comparable to some of the SNR measurements when doing injections with CALCS in aLog 21890. Note this is the same waveform injected here except in aLog 21890 it starts from 30Hz. In both cases the matched filtering starts at 30Hz. The last two have a bit higher SNR though.

I edited Peter S.'s matlab script to check the sign of these PCAL CBC injections.

Looks like the have the correct sign. See attached plots.

To run code on LHO cluster:
eval '/ligotools/bin/use_ligotools'
matlab -nosplash -nodisplay -r "checksign; exit"

Also in hindsight I should have done a couple CALCS CBC injections just to compare the SNR at the time with the PCAL injections.

I checked for overflows using TJ's script with the following command:

gwdetchar-overflow -i H1 -f H1_R -O segments -o overflow --deep  1128303500 1128303651 124

It returns an empty table, so no overflows.

A time-domain check of the recovered strain waveforms is here: https://wiki.ligo.org/Main/HWInjO1CheckSGs.  I found that the sign is correct, the amplitude matches within a few percent at most frequencies, and the phases are generally consistent with having a frequency-independent time delay of 3 or 4 samples (about 0.2 ms).  Details are on that wiki page.

I've taken Thomas/Chris' table of recovered omicron triggers for the PCAL detchar injection and calculated the ratio of expected/recovered SNR and added some comments:
