I added a simple script to /opt/rtcds/userapps/release/isi/h1/scripts/ called BRSswitch.py

You can use this to turn ON or OFF the BRS sensor correction. All this does is change the X2 and X3 matrix values in the STS2CART matrix so that when it is ON the the BRS signal is subtracted, and when it is OFF the signal stops there.

To run this script, navigate to /opt/rtcds/userapps/release/isi/h1/scripts/

Then:

python BRSswitch.py ON

or

python BRSswitch.py OFF

The purpose of this script is to eliminate confusion over how to turn it on or off and to allow for a method that can adapt to changes in the BRS system. As of now this script is specific to this BRS at EX, but can easily be made more general when/if there are more here or at LLO.
