Introduction

Like other Keck instruments, OSIRIS is always run from within a VNC session. The OSIRIS software is a combination of Java and IDL. Like all other Keck instruments, OSIRIS is really controlled via keywords and scripts that read and write these keywords. Unlike other Keck instruments, scripting is rather involved so we recommend that observers use the GUIs to take data. There are a total of 13 keyword servers that control OSIRIS. Likely, observers will not need to interact with any of these servers from the command line. The show and modify commands work on OSIRIS like any other instrument.

For numbered accounts, s is aliased to show -s osiris and m is aliased to modify -s osiris.

Procedures:
  1. Starting up OSIRIS
  2. End of the Night

  1. Starting up OSIRIS

    1. Verify that OSIRIS is ready
      2. Check SIAS or ask your support astronomer (SA) whether OSIRIS is ready for you to begin.
    2. Login to your numbered account on a 3-headed machine
      3. Look at the telescope schedule or ask your SA for the login.
    3. Start the VNC viewers
      4. When you log in, the KVNC Launch Widget should start automatically.
      1. Enter the VNC password
      2. Click Launch
      3. For the telstatus screen, click "Enable" on the "Secondary" tab, then click launch.
    4. Start the OSIRIS software
      5. Either:
      • Right-click in the VNC background: OSIRIS Control Menu -> Start OSIRIS Software
          • You will be prompted to:
        • confirm because this will change the output directory for images
        • home the motors. - answer "Y"
      • In a napili xterm, type osirisSetupNight
          • You will be prompted to:
        • home the motors. - answer "Y"
    5. Start the Quicklooks
      6. The startup script will launch the IDL Startup Widget:
      Start the 3 Quicklooks (Imager, Spec, and Online) by clicking their respective buttons.
    6. Start the Data Reduction Pipeline (DRP)
      • From the IDL Startup Widget: select DRP Backbone
    7. Take calibrations
      8. There is no need to take flats for the SPEC detector. To take IMAG flats, wait for the telescope to be released and ask your SA to make sure light is getting to OSIRIS.

  2. End of the Night

    1. Run the osirisEndNight script
      2. Either:
      • Right-click in the VNC background: OSIRIS Control Menu -> End of Night Shutdown
          • You will be prompted to:
        • confirm because this will move in the dark filter and shutdown GUIs.
      • From a napili prompt as your numbered account, type osirisEndNight.
      This will insert the dark filter in front of SPEC, copy the rectification matrices that your data require into your data directory, and create a log from the fits headers for both the SPEC and IMAG raw frames.
    2. Backup your data
