WP 12140

Per investigations described in WP 12140, I've installed elements for driving the H1 ISI HAM2 ISI in the H1 SUS PR3 suspension point's Euler basis into the ISI's H1:ISI-HAM2_SUSPOINT_EUL2CART matrix. The elements had been pre-calculated using the math from T1100617, and pulled from pre-saved collection of these matrices in 
    /opt/rtcds/userapps/release/isc/common/projections/ISI2SUS_projection_file.mat


To install, I ran the following code in matlab from a control room work station,
>> addpath /ligo/svncommon/SeiSVN/seismic/Common/MatlabTools/ % this adds fill_matrix_values.m to the path, needed below
>> cd /opt/rtcds/userapps/release/isc/common/projections/
>> load ISI2SUS_projection_file.mat
>> drvmatrx = ISI2SUSprojections.h1.pr3.EUL2CART
>> drvmatrx =

>> fill_matrix_values('H1:ISI-HAM2_SUSPOINT_EUL2CART',drvmatrx) % this actually installs the coefficients into EPICs.


These channels are *NOT* monitored in SDF. However, to make sure they stick, I've accepted the values in both the safe and OBSERVE safe snap files.
