Below is a procedure for checking out the MAGIQ guiding system as part of daily checkout tasks to prepare the instruments and telescopes for observing that night. The checkout procedure should only be completed by a trained technician.

Because some of the guiding systems use legacy hardware and other systems have more than one mechanism, it is important that the instrument technician completing the procedure to tailor the checkout as appropriate.

Complete After 2 p.m., which is after the automatic MAGIQ software process restarts. Checks of the system completed before 2 p.m. should be re-run.

Checkout Procedure

1. On the DCS GUI, select the appropriate instrument for tonight's observing session and wait for DCS to complete the initialization.
2. Restart the MAGIQ server
3. Start the OA MAGIQ GUI
4. Setup the first camera to acquire images:
   
   • Select a camera in pull down menu (e.g. lrisSlit).
   • press the Select button to select the camera.
   • Change the exposure time to 1 s
   • Change to 1x1 binning
5. Start exposing by clicking Expose and confirm image updates.
6. Change to a second exposure time, and confirm that exposure times updated. If exposure time is changed to 3 s for example, image updates will be every three seconds. Look at the last updated time stamp, located just below the image display.
   If it is failing to update exposure times
   • Select Camera->Diagnostics from the OA GUI top menu bar to lanch the diagnostic gui.
   • Select Restart Cam to restart the camera
   • For MAGIQ hardware only, power cycle the camera subsystem via the DCS/MAGIQ menu. (LRIS & NIRSPEC)
   • Call support if all the above fails to fix the problem
7. Stop here if using legacy hardware. Continue for LRIS and NIRSPEC.
8. Examine the filter wheel current positions. If any of them read "unknown"
   
   • Select Camera->Diagnostics from the OA GUI top menu bar to lanch the diagnostic gui.
   • Select Init for the mechanisms (not that.
   • Select Load defaults . to load nominal settings.
9. Test filters:
   • If exists an ND filter wheel, select ND2 and then open. If there is light, the image intensity will change significantly.
   • If exists a photometric filter wheel, elect V and then open.
   • If exists an IQM mechanism, under "Extended Camera Controls" toggle IQM between In and Out. Ignore image updates. LEAVE IQM OUT.
   • set all filter wheels to OPEN when done. IQM should be OUT.
   If any of these mechanisms fail to move,
   • power cycle the mechanisms using the DCS/MAGIQ menu.
   • If the wheel status is unknown, please then Init and then Load Defaults (power cycling should do this automatically).
   • Call support if all the above fails to fix the problem
10. Focus: Confirm a valid focus number . Should read +-1500 steps. LRIS offset is -220 and LRIS slit is 1350.
11. Stop Exposing
12. Repeat steps 4-11 for additional guiders (e.g. lrisOffset).
