OSPEC NGS-AO

Procedure:

1. In svncserver1:3 VNC desktop, select from the background menu NGS-AO Control → Start NGS calibrations
2. Keck I Calib → Calibration setup. If prompted:
   • Select OSIRIS
   • Select NGS-AO
3. Light Source Control → HEPA Off
4. Move the fiber to the optosiris named position using the PCU. Launch IDL in a k1obsao@k1aoserver terminal:

   IDL> deploy_sfpu, po="optosiris"

5. In a napili terminal, wait4ao off
6. In OOPGUI, configure a DDF to take a "dark":
   • AO type = LGS
   • LGS mode = No Laser
   • Filter = Kn3
   • Scale = 0.020"
   • Integraiton time = 2s
   • Imager settings Disabled (Spec only)
   • Click Send to queue
7. In OSIRIS Data Execution Client, click Start next dataset to expose
8. In OSIRIS Online Reduction GUI, specify the "sky" frame we just took,
   Calibration file → Specify a file
9. Move the fiber to the ospec named position using the PCU. Launch IDL in a k1obsao@k1aoserver terminal:

   IDL> deploy_sfpu, po="ospec"

10. Record a new WFS background:
    • Light Source Control → BLOCK
    • WFS Intensity GUI → Record bkgd only
11. Keck I Calib → Light Source Control → 1% = ND2
12. In the Aoacq GUI:
    • mR → 11.5
    • AO Mode: NGS-AO
    • Ref: OSPEC
    • Run Setup bench
13. Setup OSIRIS and take an open-loop image. In a napili terminal,
    • type osirisGoi spec
    This will use the same DDF to take a dataset.
    Or in OOPGUI, configure the same DDF:
    • AO type = LGS
    • LGS mode = No Laser
    • Filter = Kn3
    • Scale = 0.020"
    • Integraiton time = 2s
    • Click Send to queue
    • In OSIRIS Data Execution Client, click Start next dataset to expose
14. Check the open-loop image quality
    • OSIRIS Quicklook Online→ Tools → Peak fit → draw a box at least 5x5 pix around the point source.
    • Note the XFWHM,YFWHM.
15. Aoacq GUI → Acquire star
16. MAORI → AO Control
    • TT gain → 0.1
    • DM gain → 0.1
17. Setup OSIRIS and take a close-loop image. In a napili terminal,
    • type osirisGoi spec
    This will use the same DDF to take a dataset.
    Or in OOPGUI, configure the same DDF:
    • AO type = LGS
    • LGS mode = No Laser
    • Filter = Kn3
    • Scale = 0.02"
    • Integraiton time = 2s
    • Click Send to queue
    • In OSIRIS Data Execution Client, click Start next dataset to expose
18. Check the closed-loop image quality
    • Spec Quicklook → Tools → Peak fit → draw a box at least 5x5 pix around the point source.
    • Note the XFWHM,YFWHM. They should be around 2.3 pix.
19. Open AO loops: MAORI → AO Control → LOOP → OPEN

Back to introduction

OSPEC LGS-AO

1. Open AO loops, if they are closed: MAORI → AO Control → LOOP → OPEN
2. Light Source Control → 1% = ND2
3. Start the LBWFS Img Acq GUI, if it has not been started yet
4. In the Aoacq GUI:
   • mR → 11.5
   • AO Mode: NGS-ST
   • Ref: OSPEC
   • Seeing: 0.00
   • Run Setup Bench
   • If prompted, select Sodium dichroic

    Or in OOPGUI, configure the same DDF:
    • AO type = LGS
    • LGS mode = No Laser
    • Filter = Kn3
    • Scale = 0.02"

    • In OSIRIS Data Execution Client, click Start next dataset to expose
11. Check the closed-loop image quality
    • Spec Quicklook → Tools → Peak fit → draw a box at least 5x5 pix around the point source.
    • Note the XFWHM,YFWHM. They should be around 2.3 pix.
12. On the the LBWFS Imag Acq GUI:
    • Change the integ(s) to 1.0 seconds
    • Click Loop
13. Check the Focus ctrl and cog ctrl boxes on the Low-Bandwidth Manager GUI
14. Verify that the fast WFS COG updates on the Low-Bandwidth Manager GUI
15. Take additional OSIRIS images and check the closed-loop image quality
16. Once you are done, hit HALT on the LBWFS Imag Acq GUI, and uncheck the Focus ctrl and cog ctrl boxes on the Low-Bandwidth Manager GUI
17. Open AO loops: MAORI → AO Control → LOOP → OPEN
