Commissioning started in April. Some hours lost to problems after the thunderstorm and daytime testing prohibited because of rotator dismounting. Essentially FAPOL was found to work well. The zero angle position of the holder was adjusted. The software behaved well. Only the imaging mode was tested with both the half wave and the quarter wave plate installed. FAPOL is not designed to be easily mounted and dismounted from FASU. For this reason, changes between half-wave and quarter-wave plates must be done by staff only, and should generally not be requested during the night, perhaps not even during one observing run. It was found that we needed to adjust the holder of the calcite plate which goes into the aperture wheel in order to get the slit in the focal plane. Accurate measurements allowed us to go as close as 1mm from the focal plane without any risk of touching the folding prism. Such a holder has been made.
The FAPOL observing run which was scheduled later in April was entirely lost to bad weather. Commissioning will be continued after January 2003.
