Below is a list of tasks, most of which will be converted into engineering tasks in the CARA Remedy database. Note that there are different types of tasks: some can be done in the daytime, some are lower priority, etc. These are coded as follows:

A. Initial Setup

  1. Find any reasonably bright star, send to nominal REF pointing origin for ESI. If necessary, center using the hand paddle.
  2. Determine the TVFLIP.
  3. Determine TVANGL.
  4. Determine ROTZERO,
  5. Determine the guider pointing origin (REF).
  6. Measure the guider scale.
  7. Check guiding (pa mode, vertical mode, stationary mode).
  8. Check centering across the boundary between slitmask and pickoff mirror.
  9. * Measure the guider field distortion.
  10. * Use out of focus images to look for vignetting on guider.
  11. * Test MAlign on guider field.
  12. * Determine offset from best guider focus to best focus on instrument.
  13. Demonstrate facility scripts for moving telescope.
  14. * Demonstrate wavelength-compensated guiding (ala HIRES).

B. Imaging

  1. Determine INSTFLIP (handedness of instrument angle).
  2. Determine INSTANGL (zeropoint of instrument angle).
  3. Check operation of INSTXOFF and INSTYOFF (offsetting in instrument coordinates).
  4. Estimate imaging scale.
  5. Check rotator accuracy/repeatability.
  6. Check tracking/flexure through zenith.
