Generally, it is advisable to leave the infrared system running at the
end of a night. This allows array temperature logging to continue.
The dewar should be left blanked off to avoid prelonged exposure to
saturated light levels. Use the STARTNEWNIGHT command at the
beginning of a new night to create a new dated data subdirectory and
reset the run number.
To fully shut down the infrared system, type:
IR_SHUTDOWN
When all processes have stopped, and all but the command entry window
have been removed from the workstation screen, click on the Session
Manager (key) icon and select Quit in the Session menu.
This logs the INFRARED process out of MOPRA.
