Overlapping L1 orbits at D-PAC
The problem is not due to the operational processor (IPF), but to the input Level 0 data. In particular it is due to an anomaly in the consolidation process, which is the process of slicing the continuous measurement dataset into different orbits, from ANX (Ascending Node Crossing) to ANX. In the nomalous cases, the overlapping is already present in the input Level 0 products. However, the quality of the spectral and radiometric calibration of the data is the nominal one.

The corrective action consists in re-consolidate the orbits 26911, 26912, 27098 and 27099 at Kiruna and process the new L0 products to L1 at D-PAC.
