The ITMX CO2 flipper mirror screen was showing the annular mask turning on and off quite frequently. This was an issue with the alignment of the mask proximity sensor. We went out to the table and rotated the sensor so that it wasn't close to hitting anything.

The flipper mirrors are currently disabled and out of the beam path. The ITMX CO2 central mask is permanently fixed into place.
