h1oaf and ASC_MASTER modified

I modified ASC_MASTER today to give us the option of using AS 45 Q Yaw signals to damp roll, because yesterday we saw that this was needed for ETMX.  The model is committed, and I added an medm screen that is linked from the ASC overview and the small bounce roll monitor screen for the matrix.  The ASC model changes were done today because Adam at LLO will also work on this library part tomorow durring maintence.  

I also added log scale monitors to the oaf model, but made two typos in doing this.  I've fixed the mistakes and recompiled the model, we will wait to do a make install until the normal maintence time tomorow.

Modified matlab2010a system libraries
Modified installed Matlab 2010a system libraries to point to Ubuntu12 system libraries to allow awgstream to run.  This is an unusual request, as the control room is set up to run Matlab 2012b by default, but one user had a script which runs with Matlab2010a (but not 2012b).

Several models changed to save at top level, and committed to svn.
To correct problems with the Simulink web view of models (accessible from https://lhocds.ligo-wa.caltech.edu/simulink/) several models have been changed to be saved at the top level of the model.  If this isn't done, the top level of the model is not generated for the web view.  The models which were changed are:

h1iscex
h1iscey
h1isietmx
h1pemcs
h1pemex
h1pemey
h1pemmx
h1pemmy
h1susauxb123
h1susauxh34
h1susetmx
h1susim

There are still a few models that need to be changed.

This appears to be correctable without modifying model files by adding parameters to the slwebview() call in the matlab script.  I'll make the change in time for the 18:00 hour model web view to see if it works.

EndX HEPI On HardStops at Rotation DOFs position. X Y Z not so much

Have locked HEPI at X End.

The rotational DOFs are within ~100nrads of the closed loop running position.  The Translational DOFs were let go as the Rots were dialed in:  X -5um, Y +67um, Z +108um.  These are the deltas from the nominally servo'd position.

NPRO Tripped again
Comments related to this report
edmond.merilh@LIGO.ORG - 10:11, Monday 15 June 2015 (19148)

I'm told this was intentional. I wasn't informed.

jason.oberling@LIGO.ORG - 14:00, Monday 15 June 2015 (19153)

This was actually completely accidental.  Peter and I went out to see if we could pull a log off of the NPRO UPS as part of our investigation into this morning's NPRO trip.  Turns out that when you plug in a DB9 cable to the back of the UPS, the UPS shuts off.  We did not know this.  Now we do.  Note to self...

In other news we were not able to establish communication between the laptop and the UPS, not sure why.  Will continue to investigate.

That make me feel much better about not having gone out there alone to try it!

More quad Matlab model updates

This is a minor update to those discussed in log 18987. In addition to importing live damping filters from the sites into the model (with a 5 min delay), you can now request damping filters from a specific gps time. So svn up ../SusSVN/sus/trunk/QUAD/Common/MatlabTools/QuadModel_Production.

The requirements are the same for reading live damping filters: you must have nds2 and various corners of the noise budget svn on your computer. See the notes at the bottom of this log.

The model script, generate_QUAD_Model_Production, has instructions on how to run the model with all the various features. An example of generating a model with damping filters from a specific gps time is show here:

quadModel = generate_QUAD_Model_Production(frequency_vector,'h1etmy',[],0,true,'gps1118413940h1etmy',0,0,true,8);

* frequency_vector is some frequency vector you specify.

* 'h1etmy' is the customized H1 ETMY parameter file ('quadopt_fiber' is the general quad file). All other quads have parameter files now too, but h1etmy is the only unique one at this point.

* true (the first one) says you want damping

* 'gps1118413940h1etmy' says you want the damping filters from H1 ETMY that were running at gps time 1118413940. The 'gps' prefix is what triggers the flag to read from the given gps time.

* true (the second one) says you want violin modes

* 8 says you want the first 8 violin modes in the model (2 is the default if not specified)

I am not sure how this does foton file version control when reading the filters. It claims it is loading the foton file from the given gps time, but for all I know it is actually loading the current foton file and simply displaying the gps time you gave it. One of the noise budget experts may know more about this (the site filter reading code is adapted from the noise budget stuff, courtesy of Chris Wipf).

In general, let me know if any of these new feature do not work properly, or should be modified in any way. They have been tested on my laptop, but there could be something I have missed.

The generate script has instructions for setting up your computer to get the running damping filters from the sites (either live or from a gps time). This text is copied here:

> Follow noise budget SVN checkout instructions here

https://awiki.ligo-wa.caltech.edu/aLIGO/NoiseBudget

Checkout the following addpath paths:

svnDir = '../NbSVN/aligonoisebudget/trunk/'   (the '..' must be the same as for the SusSVN, e.g. /ligo/svncommon/)    

addpath(genpath([svnDir 'Externals/SimulinkNb/']))

addpath([svnDir 'Common/Utils/NoiseModel/'])

addpath([svnDir 'Common/Utils/'])

laser tripped
Came into the control room this morning to find that the laser had tripped.  Went to
see the Beckhoff PC and the status indicator showed "Power error (WD)" illuminated.
Not sure what caused the the reduction in power.  I do know that this morning the
lights in my office flickered a couple of times, which may or may not coincide with
the laser's power demise.  We will check the UPS log and see if it registered a switch
to batteries or something like that.

Trend data suggests the laser tripped - for reasons unknown at the moment - just after
6 am.
