===== Shutdown =====

==== Hand Off to Another Observer ====

If you are remote observing and someone else is taking over:

  - Contact the next observers to verify they are ready to observe. 
  - Save the observing log.
    * Exit from ooffice if necessary. 
  - Verify the new observers have control of the telescope and the transition went smoothly.
  - Disconnect from the vnc desktops.

==== After observing ====

  - Close the shutter, stow the telescope, turn off the DSOS, etc. Following these [[cso:observing:operating#after_observing|instructions]].
    * When remote observing, close the shutter before sunrise.
  - Stop the telescope scanning.
    * In the UIP xterm, \\ ''__uip__> **sweep /stop**''
  - Stop data acquisition. In the //Music DAQ// desktop,
    - Click the "Stop Data Acquisition" button on the Music gui.  
    - Exit the Music gui, \\ ''** File / Exit**''
    - Exit Matlab, \\ ''** File / Exit**''
  - Stop the connection between the DAQ and telescope. 
    * In the allegro xterm on the //MUSIC control// desktop, \\ ''allegro$ **kill_tel_util_music**'' 
    * Then close the two xterms in the upper left of the desktop.
  - Start a new fridge cycle. The cycle takes about 9 hours to complete. A delay can be set, but is not usually necessary.  
    - Connect to the remote desktop on the fridge control computer. \\ ''**csordp.pl -l bolocam submm@burnside.submm.caltech.edu **''
      * External connections must be tunneled through ssh. 
      * The {{cso:observing:csordp.pl}} script is recommended for managing the connections. 
      * Further [[cso:observing:ssh_rdp|instructions]] discuss details.
      * Consult the staff for the necessary passwords. 
    - Stop the temperature monitoring vi and exit from LabView. 
    - Reopen the vi by clicking the "MKIDCam_fridge_201307.vi" link on the Desktop and start it by pressing the white arrow. 
    - Select the 'PT Control and Chase Fridge Cycle' tab. 
    - Set the cycle delay in hours if you want a delay, or set to zero. 
    - Press the button to start the fridge cycle at the specified delay time. Leave the button pressed on. The green square that says 'cycle enabled' should light up bright after a few seconds.
    - Before exiting from remote desktop, switch over to the 'Temperature Plots' tab so the thermometry will be viewable on the website.
  - Stow the telescope at 35° ZA so the cryostat is upright for cycling, \\ ''__UIP__> **stow /za 35**'' 
  - Close the automated analysis xterms in the //MUSIC quicklook// desktop. 
    * Type ''**q**'' in each of the six xterms and wait for the IDL prompt to return. 
    * Then kill each xterm.
  - Perform a backup of the data. From the command prompt on lyre issue the command: \\ ''__lyre__>**/data/raw/backup_raw_data.csh YYYYMM YYYYMMDD**'' \\ where the first argument YYYYMM is the name of the current observing run and YYYYMMDD is the UT date for the recently completed night. This backup will take a significant amount of time (hours), so you should not wait for it to complete.
  - Disconnect from the vnc desktops. 
  - At the telescope, follow the [[cso:observing:operating#after_observing|instructions]] and leave the computers ready and the control room tidy for the next observers.
