A. USER STARTUP (Remote and IRTF Observers)

    The procedures for running spex for remote observing or at the IRTF are the same. Bigdog and guidedog each run in a VNC session. Observers just need to connect to these sessions. The step are:

    1. Create your Guest Account.
      Instruction for creating the guest account are located here: Guest Accounts

    2. Contact the IRTF staff for your VNC session number.
      The IRTF staff will create and start the VNC session running the XUI (User Interface) and DV (Data Viewer) for each instruments. They will give you the session numbers N, and password so you can connect to the session. For example, if N=1, the connect to "stefan.ifa.hawaii.edu:1".
      The password for the VNC session is obtained via the IRTF Staff (DayCrew or TO).

    3. Start your vnc viewer
      On the IRTF workstation, type of following command. This example assumes you display number is 1 )

        > vncviewer stefan.ifa.hawaii.edu:1

      Remote user can connect to the VNC session using their own VNC client software.
      Details on VNC operations for observers at the IRTF is found here: Using VNC with the IRTF

    4. Login into the XUI
      The XUI should present you with a login screen where you can idenity your guest account via a pull down menu. Select your guest account and press the "Use Bigdog/Guiddog using the above account" button. This will set you default data directory. We advise not changing the part before "/scrs1/guidedog/guestXX/", but feel free to modify the path after "guestXX/". After using spex, you would logout. Logging out runs a job that will set data files to be owned by and read-only by 'guestXX'.

      The pull down menu also has a 'guidedog' or 'bigdog' account selection. Choosing this will not change the saved data upon logout. The data will be own by the instrument account and be readable to all users.

    B. OBSERVER CHECKOUT (Observer Checkout- start of night)

  1. Check that no icon ERRORS are showing, check that both array temperatures are reading 30.00K (Cntl ChA 30.00K in Bigdog XUI and Guidedog XUI)



  2. Make sure the Order Sorter filter wheel is closed. OS Flt -> BLANK

  3. Make sure AutoSave is off


  4. Check Bigdog array (spectrograph). In OBS window set ITIME=1.0, COADD=1, CYCLES=1. Click green GO button at top of Bigdog XUI. An array image will appear in panel 0 of Bigdog DV. You should see array image showing counts averaging about zero and some bad pixels.



  5. Check Guidedog array (imager/guider). In OBS window set ITIME=1.0, COADD=1, CYCLES=1. Click green GO button at top of Guidedog XUI. An array image will appear in panel 0 of Guidedog DV. You should see array image showing counts averaging about zero and some bad pixels



  6. Configure Guidedog for focussing GFLT -> J, H or K (or 1% narrow-band cont-K for very bright stars)

    OS Flt -> OPEN

    MIRROR -> OUT (Lmp/Mir/Sh icon at far left)

  7. Type 'tcs1_status' in an xterm window to load the focusing widget

  8. Go to first star and focus telescope (see How to focus)

D. STAFF STARTUP (TO/Day Crew/SpeX staff only)

    If guidedog is at the 'ok', prompt, here's how to boot it:     how_to_boot_guidedog.txt

    See if the bigdog and guidedog VNC session are active using vnc -show
    If needed, start the VNC Sessions for bigdog and guidedog:

      vnc -start bigdog spex
      vnc -start guidedog spex

    Start the IC, XUI, and DV inside the vnc sesstion:


    1. IC: In bigdog's VNC session, click on "Bitdog xterm" to ssh into bigdog, type startic to start the IC.
    2. DV: In bigdog's VNC session, click on "Bigdog xterm" to ssh into bigdog, type startdv to start DV.
    3. XUI: In bigdog's VNC session, click on "Bigdog xterm" to ssh into bigdog, type bigdogxui to start the XUI.

    Repeat the above, but for guidedog.

      (open manual window cover)
      SXD mode, Dichroic open, OS Flt open, Rotator any angle
      0.3x15" slit
      cal mir in
      QTH lamp on (wait 30 sec)
      itime 1.75 sec x 1 coadd
      integrate

  3. On cybex push 'Bigdog' button, Bigdog display will appear on Viewsonic
  4. if not already there, cd current/ic
  5. type 'startic'
  6. Restart the XUI in the bigdog VNC
