To support any future LN2 dewar low-level alarms, I've started a strip tool on the virtual stripshooter server which plots a 7 day trend of all eight dewars. It is accessible from the LHO CDS home page via 'VAC (screen shots)' -> 'dewar.stp-current.png'

Attachment shows the stiptool image after it has been back-filling for one day.
