As part of the Memorandum of Understanding between the OMP team and CFHT, 5 nights were given to the instrument's PIs so they could test ESPaDOnS on science projects. The commissioning (aka Science Verification) of ESPaDOnS occurred in November and December 2004. The weather was not great, however, and some of the goals were not reached.
