The right section has a series of buttons that can be relevant to the observer:

  • Get Temp

...

  •  - Starts the temperature logging loop which is usually the last thing the observer does before ending the observing session
  • Exit LOIS

...

  •  - As the name implies, sends a message to LOIS to exit.
  • Initialize LOIS

...

  •  - Sends the initialization command to LOIS after it has been started. There is currently no way to start LOIS remotely from the UI.
  • Test Broker

...

  •  - A message to the ActiveMQ message broker to check and see whether there is a communication problem.
  • Disable Exposure - ???
  • Enable Exposure - ???
  • Stop Series/Script

...

  •  - Sends the "nstop -async' command to LOIS which causes a series or script to terminate. This does not cause an exposure abort.

Status/Info Bar

This is the place where the status of some important outside systems are displayed:

  • TCS, AOS, & DOME - The status of these systems are published to the ActiveMQ message broker and can be subscribed and displayed by any of the LOUIs. Dark yellow color implies lack of information about the state which usually happens only at start up when the telescope subsystems are not fully operational yet.
  • JOE off/on - JOE is a controller that connects the instrument to the OMS cards running the filter wheels. JOE has to be running for full operation of LMI but it is not necessary for all operations. For instance, initiating an exposure does not involve JOE but moving a filter wheel does.
  • GDR - Shows the status of the guider. As before, dark yellow implies unknown status. Red means that TCS is not tracking. Yellow implies that TCS is in open loop which means that the telescope is tracking but not guiding. Green means that the guider is active and that TCS is receiving guide corrections.

All of the above labels have tooltips which will activate by cursor hover.
