LRIS Checkout Procedure

WARNING: only authorized personnel are allowed to run the LRIS checkout script

Preliminaries

  1. LRIS should be powered up using the power gui. If LRIS was power cycled, we should run the lris Red powerup scripts. There are no scripts for the blue side.

Running the LRIS Checkout Script

  1. To start the script from the desktop menu, select the Engineering menu and then the LRIS checkout item. Three new windows will appear:
    • window for executing the checkout script
    The following message will be printed in the checkout script window: 
    ------------------------------------------------------------------------
                      LRIS OPERATIONAL CHECKOUT
------------------------------------------------------------------------

What this script will do:
  - create a new lriseng data directory
  - verify communication with the terminal servers
  - power up LRIS
  - power up guiders
  - verify that the shutter is working
  - attempt to shut down any existing LRIS GUIs
  - start LRIS GUIs
  - insert the imaging mirror on the grating turret
  - insert the "560" dichroic
  - insert the "B" filter on the blue side
  - move the grism selector to the "clear" position
  - move the slitmask selector to the "direct" position
  - move the filter selector to the "clear" position
  - turn on the Hg lamp
  - take a 1 sec exposures that are full frame images on both sides.
  - turn off the Hg lamp
  2. At the prompt 
      Do you want to continue running the checkout script? (y/n) [y]:
    press the Return key to continue. The spectrograph will be reconfigured and an image taken.
  3. The script will reconfigure the spectrograph, take a test image, then print the following message: 
    ------------------------------------------------------------------------
The checkout script has taken image which should now be visible
in the DS9 window on the RED and BLUE side. To verify the images, 
please do the following on both the RED and BLUE side DS9s:
   1) Select "Regions" -> "Shape" -> "Pojection" on the ds9 top menu bar 
   2) Click on the Zoom button located above the image area 
   3) Click on the "to fit" option to resize the display window so 
      you can see the full frame.
   4) Above the image display "Scale" button and then the "Hist Eq" 
       button to change the colormap scale.
   5) Click and drag a line from top to bottom on the display

  Inspect the resulting plot --- On the red side you should see a graph 
    with a minimum of about 1000 counts and a maximum of 30,000-55,000 
    counts, depending on:
    - which part of the chip you plotted and 
    - the current lighting conditions in the dome.  
   On the BLUE side you should see a graph with a minimum of about 1000 
      counts, and a maximum of 28,000-55,000 counts. The image should 
      show the four readout amplifiers with a brighter rectangle 
      centered in the image.
   The above red and blue values result when Dome lights are also on.
      

If things do not look as expected, please contact an Instrument 
Specialist for assistance.

  4. Inspect the output in the motor crate window. It should resemble this sample motor crate output. Feel free to ask an Instrument Specialist about any discrepancies.
  5. Inspect the output in the CCD crate window. It should resemble this sample CCD crate output. Feel free to ask an Instrument Specialist about any discrepancies.
  6. Do as the script requests to create a line plot of the image:
    1. move the cursor into the DS9 display
    2. click the ZOOM and to fit buttons to recenter the DS9 display
    3. select REGION->SHAPE->Projections
    4. Click and drag a line to make a row plot.
  7. When all looks good, press Enter in the LRIS Checkout window to quit the script. The crate sessions will be dismissed automatically.
  8. Shut down the LRIS control software by selecting the LRIS Control desktop menu option, then clicking on the Shut Down LRIS Control item.
  9. Release the instrument.

Sample Projection Plot and Images

Red Side

For the red side, note that the maximum signal should be in the range of 30,000-55,000 counts, depending on which part of the chip you plotted and the current lighting conditions in the dome.

Red side image

Blue Side

On the BLUE side you should see a graph with a minimum of about 0 counts, and a maximum of 28,000-60,000 counts. The image should show the four readout amplifiers with a brighter rectangle centered in the image. See below for an example of the image output.
