Configure UCLES to the blaze peak nearest the wavelength of highest
priority, or 5008 Å by default, using the 79 lines mm grating.

Take a 10 second exposure.
Start the FIGARO routine ROTATION.
This will use the continuum exposure, cross-correlate the top and bottom of
the frame, and calculate the amount of camera rotation required. A 4 mm
hex-key is required to loosen the clamp on the CCD mount, and the CCD can be
physically rotated to the new micrometer setting.
Take another 10 second exposure. The final image should
resemble Fig. , and be rotated to within 0.1mm (on the micrometer).
