Example Observation

The example observation shown in Table 5 consists of an acquisition phase followed by 2 exposures. In turn, each exposure consists of a choose guide star phase followed by an accumulation and tracking phase. Science data is not available for downlinking until the end of the first exposure. The status of science data, filter wheel and detector during the course of the observation is summarized Table 5. This example can be generalized to a n-exposure sequence by repeating the ``between exposures'' and ``Exposure 2'' (with suitable changes in the uplinked configuration) phases as often as required.
