FMCS medm screens

I'm confused. I was almost certain I had updated the FMCS medm screens actually linked from the sitemap. However running svn update in /opt/rtcds/userapps/release/fmcs/h0/medm gave:

U    H0FMCS_CORNERSTATION_AH3.adl
U    H0FMCS_CORNERSTATION_CY.adl
U    H0FMCS_OUTBUILDING_CY_MY.adl
U    H0FMCS_OUTBUILDING_AH_EX.adl

U    H0FMCS_OUTBUILDING_CY_MX.adl
Updated to revision 15730.

The conflict is because I had just started to edit this screen.

The screens linked from the sitemap now reflect the changes I had made. I'm not sure where I checked in the changes from if it was not /opt/rtcds/userapps/release/fmcs/h0/medm. I have a copy of these screens in my home directory but they do not seem to be an svn working copy. Did someone revert /opt/rtcds/userapps/release/fmcs/h0/medm to an earlier revision?

More confusion. The link in the SITEMAP.adl file in /opt/rtcds/lho/h1/medm points to /ligo/lho/h0/fmcs/medm not /opt/rtcds/userapps/release/fmcs/h0/medm.

/ligo/lho/h0/fmcs/medm is an svn working copy already at the most recent revision.

Perhaps something changed with the SITEMAP instead?

FRS Ticket 6024

I attach two trends of the past 12 days (three more than Daniel's plot above), and the past 365 days of these local oscillator read backs of the H1 ALS Y WFS A system. One can see from the 365 day trend that these ADCs would on drift at a rate of (the equivalent of) ~0.1 [dBm / month], so we're not going to be able to see if the problem is true fixed in these 6 days since the module was swapped.

So, my vote is that we close the ticket, but continue to monitor, and re-open if we find any drift in the future.

DCS filters for LHO data starting at 1173225472 
I have produced filters for offline calibration of Hanford data starting at GPS time 1173225472. The filters can be found in the calibration SVN at this location:
ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/GDSFilters/H1DCS_1173225472.npz

The new filters have EPICS and calibration line parameters for computing SRC detuning parameters. See
https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=35041

For suggested command line options to use when calibrating this data, see:
https://wiki.ligo.org/Calibration/GDSCalibrationConfigurationsO2

The filters were produced using this Matlab script in SVN revision 4584:
ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Scripts/TDfilters/H1_run_td_filters_1173225472.m

The parameters files used (all in revision 4584) were:
ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/params/2017-01-24/modelparams_H1_2017-01-24.conf

ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Scripts/CAL_EPICS/D20170411_H1_CAL_EPICS_VALUES.m

Several plots are attached. The first four (png files) are spectrum comparisons between CALCS, GDS, and DCS. GDS and DCS agree to the expected level.
Brief time series of the kappas and coherences are attached, for comparison with CALCS.
Time domain vs. frequency domain comparison plots of the filters are also attached.

As a sanity check, I have calibrated data from early June to test whether these filters are up to date. Spectrum comparisons between the C00 frames and these filters are shown, and some unexpected discrepancy is noted at higher frequencies. Time series of the kappas are attached as well. These agree with the summary pages (i.e., the GDS pipeline).

It is now evident that this change did not occur during the vent, as the attached ASD ratio plot is from C01 and C00 data from May 08, 2017 at 14:00:00 UTC (GPS 1178287218), right before the vent.

It seems this change occurred during maintenance on Tuesday, April 11. The first ASD ratio is from data right before maintenance activities, and the second is from right after. Also it is confirmed that this is not being caused by a difference in the applied kappas (so the EPICS records agree). The most likely culprit is a change in the inverse sensing filtering.

Relevant aLOGs around April 11th -- LHO aLOG 35474, and more specifically the comment, LHO aLOG 35476 which a "small change in writeEPICs code" is mentioned.

Can we compare the EPICs records committed to the repo around that time?

I traced the problem to the GDS filters installed on April 11: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=35462
Simply regenerating those filters seems to have fixed the problem, as shown in the attached ASD ratio plot comparing C01 to the corrected GDS filter output right after maintenance on April 11. The filters were generated as described in the above aLOG, except that the SVN revision was 4781, so the exact reason for the problem is unknown.

The C00 data affected by this problem starts on April 11 (GPS 1175976351), and it is still currently being affected, until we restart the GDS pipeline, no later than next Tuesday, June 20. The C01 frames are not affected by this and should be fine.

New GDS filters for LHO to compute SRC detuning parameters 
[Jeff K, Aaron V]

I have produced new GDS filters for LHO that include new paramters (pcal correction factors and EPICS) necessary to compute SRC detuning parameters. It will also be possible to subtract the calibration lines from the strain, producing the additional channel GDS-CALIB_STRAIN_CLEAN, if we desire. The filters can be found in the calibration SVN at this location:
ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/GDSFilters/H1GDS_1175954418.npz

For information on GDS calculations of SRC detuning parameters, see:
https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=35041  (note that we now compute Q-inverse instead of Q)
https://alog.ligo-la.caltech.edu/EVNT/index.php?callRep=11785

The filters were produced using this Matlab script in SVN revision 4537:
ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Scripts/TDfilters/H1_run_td_filters_1175954418.m

The parameters files used (all in revision 4537) were:
ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/params/2017-01-24/modelparams_H1_2017-01-24.conf
ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/params/2017-01-24/H1_TDparams_1175954418.conf
ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Scripts/CAL_EPICS/callineParams_20170411.m

ASD plots comparing GDS and the front-end CALCS model are attached. These agree with those on the summary pages from the same day (4/10), as expected. Also, time domain vs. frequency domain comparison plots of the filters are attached. Lastly, a time series plot of the kappas from GDS and CALCS is attached, as well as histograms. These show the expected output.

It was discovered that the output of these filters did not agree with the C01 frames. These GDS filters have been regenerated with SVN revision 4781, and the discrepancy has disappeared. For more details on this issue, see https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=36863 .
