Do you often wonder if the BRS on or off? Do you stay up at night asking yourself if you should have turned it off when someone went down to EX?

Ask no more! There is now a BRS Active light on the ISI EX_GND medm screen.

Operators: if someone is heading down to EX, please make sure to check that the blue "Not in use" light is lit. If it is not and the brighter blue "ACTIVE" light is, go to the wiki:  https://lhocds.ligo-wa.caltech.edu/wiki/UsefulScriptsForOperators  and follow instructions to turn OFF the BRS sensor corrected signal.

An important thing to note: this medm light does not look at the sensor correction filters, only if the appropriate matrix elements are selected. This should not be a problem since the script turns on the correct filters when switching between using the BRS sensor corrected signal (ON) and not using the BRS signal (OFF). In the near future, a Guardian node will control this rather than scripts from the command line and, hopefully, eliminate all confusion.
