Running a2l scriptS now

There are now THREE a2l scripts that we will be running once during EACH lockstretch. Patrick mentioned them in his time log. I'm tagging Opsinfo with the information again.

cd /opt/rtcds/userapps/release/isc/common/scripts/decoup

./a2l_min_LHO.py

./a2l_min_PR2.py

./a2l_min_PR3.py

that is all :)

A note on the (3) A2L measurements.  

  1. The ...LHO.py file can improve H1 performance.
  2. The ...PR2 & PR3.py files are for data-taking purposes (Jenne alignment study).

As of this week, we want to run the ...LHO.py file at the beginning of locks (i.e. right after we reach NLN).  It takes on the order of 10min.  

Sometimes you might not want to run it.  If the DARM specrtra looks good around 20Hz, then you are good.  It's a judgement call, but in general, this helps with sensitivity.  Will put this in the Ops Sticky Note wiki & should get in the Ops Checksheet soon.

(Thanks to Jenne & Ed for sharing the alogs about this!)
