Procedure: Acquire LGS WFS Data
Best performed close to zenith. Can be done on the zenith boresight position,
but does not have to be.
-
Make sure there is no stellar contamination on the WFS while the laser
is propagating and that the WFS is in the proper LGS focus position
and LGS is properly aligned on the WFS.
-
Tune off wavelength to get a fresh background.
-
Take WFS images of the background, at the shaneao prompt:
wfs_cam_run(20,0.3,comment=Rayleigh)
will take 20 images, 0.3 sec between images, comment will
end up in FITS header.
-
Tune back on wavelength.
-
Take data (in the ShaneAO loop control GUI go to Actions -
Save telemetry data) a couple of times.
-
Make a note of the data file numbers and laser power
(from the laser operator).
-
Take WFS images of the LGS at shaneao prompt:
wfs_cam_run(20,0.3,comment="LGS loops open")
will take 20 images of the WFS, 0.3 sec between each image.
-
Close the uplink and WFS loops.
-
Take WFS images of the LGS:
wfs_cam_run(20,0.3,comment="LGS loops closed")
