  2. Start up the  Instrument Control Computer (ICC)
    1. Wake up the Instrument Control Computer (ICC), the iMac on the left of the control console.
    2. Close windows that are not needed by you (HKP, DTP, SCP, QLP, IGRINS Hub) on the Desktop if they happen to be open. HKP and the IGRINS Hub should have been open, make sure to close them now. Do not touch any terminals that have tmp350.py, hk_to_firebase.py, and test_mnt running, just in case they happen to be visible
    3. Open IGRINS Proxy
      1. Open a terminal
      2. > cd ~/igrins_admin
      3. > sh tcsproxy.sh
    4. Open IGRINS Hub
      1. Open a terminal or another tab
      2. > cd ~/igrins_admin
      3. > sh ics_hub.sh

      3. Check terminal windows to see if run_hk2firebase.sh is running (This is what updates the website monitoring IGRINS)
          1. If it is not running, then start it up by...
            1. Open a terminal window or tab
            2. > cd ~/igrins_admin
            3. > sh run_hk2firebase.sh
      4. Start up the Slitview Camera Package (SCP) by clicking "Run SCP" in the IGRINS Hub
        1. Check if you are receiving the TCS information or not (blue values on the upper right, including RA, Dec). 
        2. In the Status box, the following lines should appear: 
          1.  “[time] NFS connection succeeded”
          2. “[time] Detector Status Check”
          3.  “[time] Detector is Ready” 
      5. Start up the Data Taking Package (DTP) by clicking "Run DTP" in the IGRINS Hub
        1. In the Status box, the following lines should appear for both the H and K detectors: 
          1.  “[time] NFS connection succeeded”
          2. “[time] Detector Status Check”
          3.  “[time] Detector is Ready” 
        2. Change the observer name to your Last Name. No single quotes or special characters. Commas are ok.
      6. Open the Quick Look Package (QLP)
        1. Open a terminal window or tab
        2.  > cd igrins/igrins_admin
        3.  > sh run_qlp.sh
        4.  This will open two different windows (each H and K).
          1. In the K window, click 'OPEN' and go to the 'obs_data' directory (this folder is conveniently found in the window that opens on the top left) and find the K image that you want. Do the same with H.
          2. Checking the "fits" button will enable you to look at a specific image, or alternatively, the "Auto Refresh" button will update with each newly obtained spectra.
          3. Click on the thumbnail image on the right (a yellow box overlay will appear). Adjust the scale, etc. as needed and hit apply, but you must click again on the thumbnail image to update the larger image.
    6. Take test exposures to check to make sure readout of detectors with the ICC are working
      1. On the SCP...
        1. Uncheck "Automatically Save"
        2. Check to that exposure time is set to 1.63 seconds and Fowler Sampling Number is 1
        3. Click "Single" to take a single test exposure
        4. If you see noise pattern or low-resolution image, repeat the short exposures or contact observing support
        5. Hopefully it will work fine
      2. On the DTP....
        1. Uncheck "Automatically Save"
        2. Set exposure time to 1.63 seconds
        3. Set Fowler Sampling Number to 1
        4. Make sure Repeat Number is set to 1
        5. Click "Single" to take a single test exposure
        6. Hopefully both detectors will read out fine, you should hear the computer say "H finished" and "K finished"
        7. If you see noise pattern or low-resolution image, repeat the short exposures or contact observing support
        8. When finished, check "Automatically Save" so you don't forget to save your calibration frames
    7. The ICC should now be set up for the night.  Now onto taking calibrations.
  3. Starting up the Telescope and Taking Calibrations
    1. Go out in the dome
    2. Go to the old control room and press each of these buttons:
    3. Go to the console and press "Reset".  You will here a click as the breaks preventing the telescope from moving are released. There should be no messages on the TCS now.
    4. Point the telescope at the Flat position
      1. Go to TCS, click the "Next" menu, click "Flat", and click "Yes" on the warning message that pops up
      2. Click "Go Next" at the top of the TCS window
      3. Push the Autoslew button to move the telescope to the Flat position
      4. Use the yellow hand-paddle to move the upper windscreen all the way down to reveal the full flat screen.
        Image Added
      5. Use the hand-paddle to manually move the dome to the Flat position so the black and clear tape on the east side of the dome match up.  Typically you want to slow down the dome movement rate to ~50% when doing this
        Image AddedImage Added
      6. Raise the east platform so you can reach the top of IGRINS
        1. Check console to make sure telescope mirror cover is closed for taking darks
        2. Make sure the shutter on top of IGRINS is closed for taking darks
          Image Added
        3. Unravel the Flat lamp power cord tied to side of telescope by undoing bungee cable and the two velcro ties
          Image AddedImage Added

        4. Test that the Flat lamps are working by plugging in the power cord.  The flat lamps should turn on.
          Image Added
        5. Unplug power cord to turn flat lamps off for now because we will start by taking Darks
        6. Turn off dome and passage lights on the console for taking Darks
        7. You can leave the east platform raised while taking calibrations

 

 

 

Instrument Startup

  1. Wake up the Instrument Control Computer (ICC), the iMac on the left of the control console.
  2. Close windows that are not needed by you. Please leave the terminal running hk_to_firebase.py running in the background.
  3. Ensure that TeamViewer is running on the ICC - blue box with two arrows on the top taskbar.
  4. Start the TCS proxy by opening a terminal, and typing 
    1. > cd ~/igrins_admin
    2. > sh run_tcsproxy.sh
  5. The TCS proxy is required for the IGRINS software to communicate coordinates and moves with the telescope. 
  6. Changes to the instrument PA need to be input into the TCS proxy in order to propogate to the IGRINS software. The default PA is 90.
  7. Start the ICS Hub by opening a terminal and typing 
    1. > cd ~/igrins_admin
    2. > sh run_icshub.sh
  8. The ICS Hub allows you to:
    1. Adjust the output directory of your data. This is useful if you restart the computer near the end of the night.
    2. Check the status of the hard drive mounts. They should be 'Okay'. Otherwise you need to type
      1. > cd ~/igrins_admin
      2. > bash mntrun
      3. and enter the IGRINS password
    3. Check the Proxy status. Should be 'Okay'.
    4. Start the Housekeeping package, Slit Camera Package, and Data Taking Package.
  9. On the HKP window, click the "Periodic Monitoring" button. 
  10. Take short exposures on SCP and DTP to test readout. If you see noise pattern or low-resolution image, contact observing support. 
  11. The QLP should have updated when the test exposures are done.
  12. IGRINS is now setup for the night.


...

      • Turn off ‘automatically save’ if you prefer
      • Use shortest exposure 1.63s

 

 

If you see noise pattern or low-resolution image, repeat the short exposures or contact observing support.
