      Most notably it was discovered that the incoming Doppler data from ESA 
      and thus level 1a and level 1b Doppler data may contain a wrong uplink 
      frequency. This problem was identified during processing and corrected 
      for level 2 data. If this problem occurred the folder 
      UPLINK_FREQ_CORRECT will be generated in the CALIB directory containing
      information which raw files were effected and where to find the         
      corrected data.

      It was discovered later in the mission that for IFMS the file naming
      convention of AGC (Automatic Gain Control) raw files was crossed since  
      beginning of the mission. In fact AGC1 refers to D2 and AG2 refers to   
      D1 and not the other way around as it should be. Consequently the AGC 
      files were swapped during the whole processing.

      Anomalies which ocurred during measurements such as wrong sample rate
      or wrong timing which might affect the quality of the data are listed
      in CATALOG/DATASET.CAT under anomaly report near the end of the file.

      Possibly contains one of the files, which are listed in the
      Sorce_Product_ID in LEVEL02, files, which do not belong to the
      measurement. These files were only used for processing. Therefore one
      cannot find according LEVEL02 files. These, for the processing used
      files, do not affect the LEVEL02 files.
