Anomalous scan pattern

After an IDU anomaly occurred on 23 September 2008 the instrument was manually put back to measurement at ESOC, however not all the CTI were correctly uploaded to the platform, so that the instrument measured using a non-intended scanning pattern, in particular the start altitude was the UA one (around 100km) while the altitude spacing was the one of the NOM. The problem was detected at ESOC and the instrument was stopped for few minutes in order to upload all the CTI for the planned UA measurements. The anomalous scan pattern impacted about 7h of MIPAS measurements as can be seen in the figure below.





All the MIPAS measurements taken during this period have this anomalous scan pattern and the L2 processing of these data will be strongly affected.
