Minimize Sensor Modes

The MIPAS full-mission data set from routine operations starts from the 1st of July 2002 (orbit 1746) with last orbit acquired on the 8th of April 2012 (orbit 52867). The acquisition baseline was defined by a Science Team in the MIPAS Mission Plan Rationale, and had been regularly revised along the mission in order to adapt the measuring scenario to scientific requirements, such as special operations in support to calibration/validation campaigns or special events. Different measurements modes were thus implemented.
In addition, the Interferometer Drive Unit major anomaly in 2004 (see Mission Operations Overview), obliged ESA to modify the acquisition scenarios and the mission target itself (ref. MIPAS Mission Plan document).
