How To Setup ARGOS for AO calibrations

Pre-requisits:
  • Coordinate telescope access with Telescope Manager and mail to telescopework
    • Telescope must be at Zenith - you can check it in the IIFGUI.
    • Stow pins must be in - you can check it in the MCSGUI.
    • HBS should be on - you can check it in the MCSGUI.
    • Authorize as LUCI, bentGregorianArgos (HowToAuthorizeLUCIAtARGOS) - you can check in the IIFGUI)
    • Set the Adsec Shell in Adsec Control GUI
    • Enable Retroreflector mode from the adsec terminal (enable_rr_mode.sh) - you can check in the AOSGUI (details in HowToEnableDayTimeModeInTCS)
    • Upper floods must be switched off, lowers can be on
  • Now done with authorization as bentGregorianArgos:
    • Fiber switch must connect ARGOS BCU to Adsec - (HowToUseTheFiberSwitch ) - (now done with authorization of bentGregorianArgos)
      • not yet fully:
        • Go AdSec Control GUI: Tab 'Focal station' -> Press 'Set'
    • Enable Argos Arbitrator in AOSGUI - (now done with authorization of bentGregorianArgos)
Procedure
  • Startup ARGOS and SOUL softwares, see HowToStartSoftware and HowToStartPyramidWfs
  • Open Arbitrator GUI.
  • Put LAS and LAN in simulation: In the ARGOS Arbitrator GUI, Tab: Expert->Commissioning.
  • Execute the operation sequence by clicking on:
    • "1. Power Up" (wait until status is POWERED_UP). Note that this step waits for the PnCCD to be cold, so it takes a long time.
    • "2. Set Up" (wait until status is SET_UP)
    • "3. Start Up" (wait until status is STARTED_UP)
  • SOUL-WFS power up and ready.
  • Get system to "READY_TO_CALIBRATE_ON_CALSOURCE" (pressing "Prepare"). Make sure that Light source is "Calibration source diodes".
  • [Parallel] Deploy calibration unit, see HowToSetupCalibrationUnit
  • [Parallel] Setup Hexapod: see HowToEnableHexapodOffload
  • [Parallel] Switch on White light source (shutter position 100)
  • [Parallel] Switch on Diode sources (100mA current)
After finishing all previous tasks you should see the CalSourceDiodes on the Patrol cameras (Arbitrator GUI, tab "LGS Acquisition").
  • If not visible you have to search for them with the Hexapod
  • If you see large coma you can remove it following HowToRemoveComa.
  • If they look good you put them on the wavefront sensor
    • Open 'CCD viewer': Applications -> Argos ?x -> ccd viewer
    • Open Arbitrator GUI, tab "LGS Acquisition".
    • Select "hexapod & patrol camera"
    • Click on each of the camera displays on the corresponding spot of the beacons.
    • Press button "Acquire manually".
    • Repeat until pattern on "CCD viewer" looks good.
    • Update in PSFGUI the Hexapod "Global Offsets" with the values from "Platform Position"!
