We'll debugging the Y-ARM alignment during initial alignment, we went back to the camera archive,
    /ligo/data/camera/archive/${YYYY}/${MM}/${DD}
and found -- comparing against the live camera -- that the mask that is used to calculate the centroid for the ITM green camera is poorly aligned with the green spot on the camera. 

This is just a note that we should fix this once we're happy with an alignment that gets the IFO back up.
