This is a short summary of normal IGRINS startup sequence for observers.use for observers at the McDonald 2.7m telescope 

Beginning of night Procedure:

1. On Atlas
   1. Log in with IGRINS account
      1. Ask for username and password if you do not already know it
   2. Open night log on Atlas
      1. Open a terminal and type "dr"
      2. Fill out observer name(s)
      3. Set instrument to IGRINS
      4. Check for any notes from the McDonald Observatory staff
   3. Open TCS GUI on Atlas
      1. Open a terminal and type "tcsgui"
   4. Open monitoring cameras
      1. Open firefox and go to http://nexus.as.utexas.edu
      2. Click "Observing support"
      3. Click "monitoring cameras"
      4. Right click "MONET Sky Camera" and open in new window
      5. Right click "2.7m Tube camera" and open in new window
      6. Right click "2.7m Dome interior" and open in new window
         1. You can shrink size of 2.7m Dome Interior camera image by clicking "1x"
            
      7. Rearrange monitoring camera windows on the Atlas screens to your preference
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
   5. In the IGRINS Hub...
      1. Make sure Update Obsdate is the correct (civil) date
      2. Start up the Housekeeping Package (HKP) by clicking "Run HKP"
         1. In the HKP...
            1.  click "Start Periodic Monitoring"
            2. Make sure "Set Alert (T > 30)" box is checked
      3. Start up the Slitview Camera Package (SCP) by clicking "Run SCP"
      4. Start up the Data Taking Package (DTP) by clicking "Run DTP"
   6. \

1. Wake up ICC on the right (a big iMac) and close these windows (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, sh_to web.sh, and test_mnt running, just in case they happen to be visible - these will often be running on a different Desktop window so you do not see them. As such, your work should be be limited to Desktop 1 and 3.

2. Turn on the IG proxy by clicking the icon on the top right corner of the iMac desktop.

3. Turn on the IG software (HKP house keeping package, SCP slitview camera, DTP data taking package) by opening a new terminal and typing:

> cd ~/igrins_admin
>sh icsrun_dct.sh
When it launches, the "IGRINS Hub" window will pop up.

You should see the "check Mount" and "check Proxy" change from "..." to "Okay" status.

Start the HKP (click "run HKP"). In the HKP gui, click the “periodic monitoring”  and, below that, the “Send Alert (T>20)” buttons.

Once you see that the HKP status says "connected" in the Hub, start the SCP (click "run SCP"). You should see the SCP window pop open.

Once you see that the SCP status says "connected" in the Hub, start the DTP (click "run DTP"). You should see the DTP window pop open.

4. Check the software

In the SCV, check if you are receiving the TCS information or not (blue values on the upper right, including RA, Dec). 

Note -  TCS will not be running without your TO. Images and cals can still be taken but headers will be incomplete.

In the Status box, the following lines (for the SVC, and then for both H and K in the DTP) should appear:

• • •  “[time] NFS connection succeeded”
    •  “[time] Detector Status Check”
    •  “[time] Detector is Ready” 

5. Test Exposures

Change the observer name to your Last Name. No single quotes or special characters. Commas are ok.

Change the object name to 'test'.

Take a test image on both SVC and with the HK detectors to test readout.

• • • 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.

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. In the left-bottom screen, open another terminal and run the Quicklook Packages (QLP) for the H and K detectors.
11. Take short exposures on SCP and DTP to test readout. If you see noise pattern or low-resolution image, contact observing support. 
12. The QLP should have updated when the test exposures are done.
13. IGRINS is now setup for the night.
