The ALS end station shutters have temporarily been commented out of the guardian. (They will no longer close, even in the shuttered state).  The goal is to have green light locked in the arms while we are at a good sensitivty, with the idea that this could possibily be helpfull for determining if some of the glitches we see are due to dust.  ( alogs 20395 20355 20328 )

We had originally added the closing of the shutters since we heard that it improved the noise at LLO, even though we saw no evidence that it improved our noise here.  After a few weeks of engineering run we should revert this change.
