Collimator problems

Since 2 Aug 2002 the collimator has been stuck. Initially it was stuck at a position that produced significant distortions in the spectroscopic spatial profiles. On 20 Oct 2002 we moved the collimator while the instrument was warm, to a position that gives better spectroscopic IQ. The collimator is likely to remain in this position for some time.
