NGS-AO (required for both, NGS and LGS calibrations)

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. After cal setup, SFP should be at optosiris. If not, run the cal setup script again.
4. In a napili terminal, execute /home/osrseng/syeh/osiris_ao_cal_checkout
5. This script will

    
       Send SFP to optosiris (if you have already run the ao cal setup and SFP is not at telescope)
   
       Configure OSIRIS with
       set wait4ao off
       set spec filter = Kn3
       set spec scale = 0.020"
       set coadds = 1
       set integration time = 2 s
       take a "sky" exposure 
     

6. In OSIRIS Online Reduction GUI, specify the "sky" frame,
   Calibration file → Specify a file
   then hit "c" to contunue.
7. The script will take an open-loop image by

    
       Send SFP to ospec 
       Block the light source
       Turn off HEPA
       Take a WFS background 
   
       Configure OSIRIS with
       set wait4ao off
       set spec filter = Kn3
       set spec scale = 0.020"
       set coadds = 1
       set integration time = 2 s
       take an exposure 
     

8. 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.
9. In the Aoacq GUI:
   • mR → 10.6
   • AO Mode: NGS-AO
   • Ref: OSPEC
   • Run Setup bench
   • Acquire star and wait for loops to close
   then hit "c" to contunue.
10. The script will take a close-loop image by

     
              Lower the TT and DM loop gain to 0.1
              Configure OSIRIS with
              set wait4ao off
              set spec filter = Kn3
              set spec scale = 0.020"
              set coadds = 1
              set integration time = 2 s
              take an exposure 
        

11. Check the close-loop image quality
    • OSIRIS Quicklook Online→ Tools → Peak fit → draw a box at least 5x5 pix around the point source.
    • Note the XFWHM,YFWHM, they should be around 2.2 pix.
12. Hit "c" to finish, and the script will

      
          open the TT and DM loops
          
      

Put everything in safe mode

• Put in dark filter for OSIRIS spectrograph: in OSIRIS napili terminal, type m sfilter=drk
• Keck I calib → Dismiss
  • If AO loops are still closed, select Open loops
  • Select Turn HEPA ON
  • Put WFS in standby if night observations are going to start in the next one or two hours, select YES, otherwise select NO
  • Turn the light OFF
• Move the SFP to the telescope position in three steps, otherwise SFP will fault. In the SC GUI
  • SF (SFP) → obsfname → prehome (wait until INPOS)
  • SF (SFP) → obsfname → home (wait until INPOS)
  • SF (SFP) → obsfname → telescope
• In the background menu NGS-AO Control → Stop most NGS-AO Software
