Follow these steps to shut down DEIMOS and associated systems at the end of the night.

  1. If you are taking calibrations after observing, disable DCS control.
    This will only disconnect the DEIMOS rotator from the telesecope control system, but it will keep all the GUIs running.
    1. On the DEIMOS instrument control GUI, click on the Rotator → Details... button to bring up the rotator GUI
    2. Click on the Sky mode label to activate the rotator sky mode buttons.
    3. Click on Disable DCS.
    The rotator should be halted a few seconds afterwards. You can now take after-observing calibrations. Once you are done with your calibrations, run the End-of-Night Shutdown.
  2. If you are NOT taking calibrations after observing, perform End-of-Night Shutdown.
    This option will put DEIMOS in safe mode and shutdown all GUIs. From the background menu, select DEIMOS Control Menu → End-of-Night Shutdown. This will perform the following functions:
  3. Exit Firefox.
    If you were using Firefox, kill the existing instance of the web browser.
  4. Specify any configuration changes.
    If you will be observing with DEIMOS again tonight and need to alter your instrument configuration based on what you did or did not accomplish, use the DEIMOS online run configuration form to modify your list of gratings, filters, and slitmasks.
  5. Remove starlist.
    If it is important to keep your targets confidential, be sure to delete your starlist file.
  6. Electronic Log.
    The electronic log will be accessible on the program's PI Keck observer page within one or two days of the observing run.
  7. Backup your data.
    See detailed information on data backup.
  8. Complete POC form.
    Please complete a Post Observing Comments form to let us know how your run went. You responses to this form are logged and tracked and are important to us in maintaining and improving nighttime observing operations.
  9. Log out (remote observing room).
    From the local desktop menu (not the VNC one), select the option to log out. At Keck this is done by selecting Exit FWVM on the local (not VNC) desktop menu; at other sites it will depend on your site's configuration. It is not necessary to close your VNC viewers, since they should close when you log out.
  10. Take your stuff (remote observing room).
    Before leaving remote ops, please be sure you have all your belongings and throw away any trash.
