Results for the March 2007 service mode

This night had very good consistent seeing (0.6 arcseconds), and was classified by VISIR as fair to good. Service mode operations with MIDI on the G0-K0 baseline produced a lot of observations, all of which were classified A or B. Two calibrators were observed three times each, on with HIGH_SENS and the other on with SCI_PHOT. We can show here that the latter mode produced slightly better results.

We have also reduced the photometry and show that one of the beams (B, G0) is significantly better that the other one in terms of stability.
